Avogadro's number is defined as the ratio of entities(atoms or molecules) in a sample to the ammount of substance(mole) through the relationship. It has been described as the factor that relates the molar mass of the atom or molecule, for example, the mass per ammount of substance, to the said atom or molecule. Avogadro's number expresses the amount of atoms or molecules per mole of a substance, and is said to have a number of 6.02214179(30)x10^23. Asuming that one gram of Cl is 35.453, then 15 grams should contain 3.626618825x10^26.

Avogadro's number is defined as the quantity of atoms in exactly 12 grams of 12C. This number, or constant, was named after Avogadro because he stated that the volume of a gas is proportional to how many atoms it has. To be more precise, this number is expressed as 6.02214179 x 1023 mol-1. This is related to atomic mass because this constant is used to calculate the amount of atoms in a certain amount of space. There are exactly 2.36353333 x 6.0225 × 10 to the 23rd power atoms in 15 grams of chlorine, or 1.423 x 10 to the 24th power atoms.

Avogadro's number is a number representing the number of molecules in one mole which is equal to 6.0221415 × 10^23 Approx. 602,250,000,000,000,000,000,000. Avogadro's number and atomic mass is related because if you can find the atomic mass of a number then you can multiple it by Avogadro's number then you can find the atoms mass. If Cl mass is 35.453, their are 5.88920266 × 10-23 atoms in 15g.

Avogadro's number is the number of molecules in on mole. It relates to atomic mass because you use it to find the amount of atoms in a certain amount of space by multiplying the atomic number. Knowing the atomic number of Cl, 35.435, we can figure out that in 15g of Chlorine there are 218 302.659 atoms or molecules.

Avogadro's number is basically a representation of the ratio of entities, Or atoms and molecules, to the substance, wiki says substance is measured in mole which means nothing to me. The actual number is 6.0221415 x 10^23 or something like that. This is related to the mass of an atom or atomic mass is that if you multiply it by the really big Avogadro number, then you can find the atomic mass. Soooooooo if the mass of 1 chlorine atom is 35.453, then you can use Avogadro's number to fugure out that there are 5.89 x 10^23 (i rounded) atoms in 15g of chlorine. (Pretty Smart Huh?)

Avogrados number, by definition, is the number of molecules in a mole (represented as mol) of a substance. It is also equal to the number of atoms in 12g of Carbon-12. The exact number would be 6.022137 X 10^23, meaning that one mole is equal to approximately 6.02 X 10^23. Avogrado's number relates to atomic mass because since atoms and molecules are so small that they cannot be counted by observing them,we use this indirect method to find out the number of atoms or molecules in an element/ compound. To find how many atoms are in a given mass of a certain substance, we use the formula: given mass/molar mass X Avogrado's number. This means that in 15g of Chlorine there are 2.54794016 (aprox. 2.55) X 10^23 atoms.

Since atoms and molecules are so tiny, they cannot be counted by direct observation. One of the ways that they are counted is using Avogrado's number. Avogrado's number is the number of particles found in the mole of a substace. It is the number of atoms found in 12 grams of carbon-12. The number is approximatly 6.022137 x 10^23 particles per mole.It is related to atomic mass because the weight of an atom may be calculated back from the atomic weight by dividing it by 6.022137 x 10^23. If Cl mass is 35.453, there are approximatly 5.89 x 10^23 atoms in 15g of Chlorine.

The mole is defined as the quantity of a substance that contains the same number of “units” as the number of atoms in 12 grams of Carbon-12. This number can be represented by 6.02 x 10^23 and it is known as Avogrado’s number. In other words, Avogrado’s number is the quantity (or number) of atoms in precisely 12 grams of Carbon-12, which is 6.02 x 10^23. Avogrado’s number is directly related to atomic mass. Atomic mass is calculated by finding the weight (in grams) of 6.02 x 10^23 of an element. If Cl has a mass of 35.453, there are about 2.5 x 10^23 atoms in 15 grams of Chlorine.

Avogadro's number is the number of molecules in a mole of substance which is 6.02 X 10^23 or approximately 602,250,000,000,000,000,000,000. Avogadro's number is the number of atomic mass units in 1 gram. It is defined in that manner so that the atomic mass of an element is numerically equal to the number of grams of the element per mole. If Cl mass is 35.453, there are 531.795/mol Cl. Using Avogadro's number I was able to find the solution by using a proportion.

Avagadro's number is approximately 6.022 x 10^23, and is the number of atoms in a mole. A huge number much greater magnitude than we can picture. It is the number of atoms in a mole, and the atomic mass is the weight of 6.022e23 particles of that element. Avagadro's number can only be known to the precision that the number of atoms in a measureable weight of a substance can be estimated. There are 2.55e23 atoms in 15 grams of Cl.

Avogadro's number is 6.0221415 x 10^23, which is the number of atoms or molecules in a mole. It relates to atomic mass because you can use the formula to find the mass of an atom. In one gram of Cl there should be about 5.8871 because you do 35.453/6.0221416 and that equals 5.8871 x 10^23 in 15 g of Cl.

Atomic mass is the addition of the mass of the protons, neutrons, and electrons in an atom. Since the mass of electrons is so little some people don't add it into the atomic mass. Avogadro's number is defined as the quantity of atoms in precisely 12 grams of 12C or the ratio of entities in a sample to the amount of substance through the relationship. The number is given as 6.02214179 x 10^23 mol^-1. Avogadro's number is related to atomic mass because to get the number of atoms in an elements you multiply Avogadro's number with the elements atomic mass.

Avogadro's number is 6.02214 X 10^23 which represents the number of molecules in a mole of a substance. It's related to atomic mass because you can use Avogadro's number to convert units of a substance to get the amount of atoms that make up that substance. If Cl mass is 35.453, then there are 3.202544 X 10^26 atoms in 15 g of Chlorine.

Avogadro's number is named after Amadeo Avogadro. Basically, Avagadro's number is equal to 6.0221415 x 10^23 due to "the number of atoms present in 0.012 kilograms of isotopically pure Carbon-12". Also explained by the amount of "elementary entities comprising one mole of a given substance". Avogadro's number relates to atomic mass because to find the mass of an atom all you have to is multiply it the atomic mass of your substance by Avogadro's number. If Cl mass is 35.453, then in 15 g of Chlorine there should be 2.135029826E25 atoms

Avogrado's number is the amount of atoms or molecules per mole of a substance. 6.022137 × 10^23. Avogrado's number relates to atomic mass because when an elements atomic mass is multiplied by Avogadro's number, what results is the atom's mass. Cl mass is 35.453, then 15g of Chlorine would contain 2.135 X 10^25

Avogadros number is the number of "elementary entities"in one mole, that is the number of atoms in exactly 12 grams of carbon-12. These two have to do because by using avogadros number is more like a formula to figure out a amount of atoms in a certainamount of a substance.According to his number i bealive their are 3.202544739x10^26 atoms in 15g of cl.

Avogrado's number is basically a number that represents the number of molecules in one mole which equals to 6.0221415 x 10^23, also equal to 602,250,000,000,000,000,000,000.

The Avogadro's number is used to find the amount of atoms in one space. If Cl mass is 35.453, their are 5.886758 x 10^-23 in chlorine. I got this by dividing 35.453 by Avogadro's number.

Avogadro’s number is the number of atoms in a substance depended on the substance’s quantity. The term use to describe Avogadro’s number is a mole, or mol, which is equal to about 6.0225x10^23 atoms. Now in a way Avogadro’s number relates to atomic mass. The atomic mass of a substance is the average relative mass of the substance and its isotopes. The number 6.0225x10^23 is the number of atoms in 12g of carbon-12, and this is the basic foundation of all atomic masses of any element and isotope. In essence a mole of helium is the same amount of mass as its atomic number.

Now the problem before me is: the number of atoms contained in 15g of carbon. 1 mole of chlorine has a mass of 35.453g. So, 15 grams should contain, 2.54809184x10^23 atoms.

Avogadro's number, or Avogadro's constant, represents the number of atoms in 12 grams of 12C, which is approximately 6.02214179 x 10^23. Avogadro is famous for his quote, “Equal volumes of ideal or perfect gasses, at the same temperature and pressure, contain the same number of particles, or molecules.” This basically means that if any two gases are under the same conditions and have the same volume, they will have the same amount of molecules. This can be used to find the number of atoms in a specific volume of any "ideal or perfect" gas. Because of this you can determine that the number of atoms in 15g of Chlorine is approximately 7.5276772375 x 10^23.

Avogadro's number is the numbers of particles that a delivers a mole of a substance. His number is 6.0221415 × 10^23 approximately. Avogadro first proposed that the volume of gas is proportional to the numbers of atoms or molecules regardless of the nature of the gas. This relates to the atomic mass because by knowing the mass, you can multiply it by avogadro's number and you can find the mass of one atom. In fifteen grams of chlorine, there are 2.13515 x 10^25 atoms in fifteen grams of Cl.

Avogadro's number or mole, is 6.0221415 x 10^23, it relates with atomic mass because with this number you can find the mass of an atom, not just the atomic mass in total. and if Cl mass is 35.453, there are aporoximatly 3.202533893*10^-23

Avengadro's number is 6.0221415 × 10^23 approximately which is the number of atoms or molecules in a mole. It relates to atomic mass because when you find the number's atomic mass you can just multiply it by Avendagro's number and then you can find out ehat the atom's mass is. If CI mass is 35.543 then their are 5.31795 X 10^2

Avogadro's number is defined as the amount of molecules in an atom. The number is 6.02214179 x 10^23 mol-1. This is related to atomic mass because this is used to calculate the amount of atoms in a certain amount of space. If the mass of Cl is 35.453, then 15 g should be 5.88710815 ^-23 atoms.

Avogadro's constant/number relates the number of atoms in a material to its mass. It is approximately 6.022137 * 10 ^ 23. The constant is the amount of atoms in 12 grams of Carbon 12. A mole of an element is X grams of the element, where X is the atomic mass of the element. In a mole of an element, there are an avogadro's constant atoms of the element. Therefore, the atoms in an amount of Y grams of an element is the constant divided by atomic mass of the element times Y.

There are approximately 2.55 * 10 ^ 23 atoms in 15g of Chlorine.

Michael Parrott 9/21/10 7 Avogadro’s number is a number that expresses the number of molecules that are in a substance per set volume at ideal pressure and temperature. Avogadro’s number, basically expressed, is 6.022 x 1023 per mole of a substance. The atomic mass of the element does not matter; all gases have the same amount of molecules per mole. One mole of chlorine is 36.453 g. So using Avogadro’s number, 15 grams of chlorine will have 2.478 x 1023 molecules. http://www.chemistry.co.nz/avogadro.htm

The atomic mass unit (amu) is defined to be exactly 1/12 of the mass of a C-12 atom. Thus, 1 C-12 atom has a mass of exactly 12.00000000 amu. 1 amu is a very small unit of mass - specifically 1amu = 1.66053X10^-24 grams. Therefore, 1.00 mole of C-12 atoms has a mass of 12.0000000 gram. Avogadro was the first to state that a gas' volume is proportional to how many atoms it has. Avogadro's number is 6.02214179 x 10^23. It is related because if you know the atomic mass of a number then you may multiple it by Avogadro's number then you will get the atoms mass. If CI's mass is 35.453, then their are 2.135156925 x 10^25.

Avogadro's number is a constant which proves that the mole of a gas is proportional to the number of atoms it has regardless of its nature. It is valued at 6.02214179(30)×10^23 mol-1. Avogadro's number has a measurement and it is the reciprocal mol (-mol). If there are 15g of Cl, then there are 2.54*10^23 atoms in that amount.

Atomic Mass is a number which is represented by adding the masses protons, neutrons, and electrons. Avogadro's number was found by an Italian scientist, Amedeo Avogadro. The number itself refers to the number of molecules of any gas in a volume of 22.41L. The number is 6.022X10^23. It relates to atomic mass because it helps you find out the calculations of a mole. One mole of a "perfect" gas occupies 22.4 Liters, at a pressure of 1 atm, and at 0 degrees Celsius. The Cl atoms are 1.422 * 10 ^24

Avogardo's number is the number of atoms or molecules in a mole, It's 6.022137 × 10^23. It was invented by a French man named Amadeo Avogardo. It's related to atomic mass because this is used to calculate the amount of atoms in a certain amount of space. If Cl mass is 35.453, then i multiply it by the Avogardo number, so 35.453 × (6.022137 × 10^23) which equals to 2.135028231 × 10^25. Then i multiply it by the 15 grams, which equals to 3.202542346 × 10 ^26, about 3.2 × 10 ^26

Avogadro's Number or Constant states that the quantity in any one mole of any substance is equal to 6.02214179 x 10^23. This is related to atomic mass because if you find Avogadro's Number and the atomic mass you can mutiply them and they give you the atoms mass. If Cl has a mass 35.453 then mutiply that by 6.0221415 x 10^23. so it would be approximately 213.5029825995 x 10^23

Avogadro's number is a number that tell you the number of molecules in in a mole. A mole would equal 6.02214179×10^23. It relates to atomic mass because with the atomic mass you could find the amount of atoms in a certain place. If Cl mass was 35.453 there would be 3.626618825x10^26.

Avogrado's number is a law that was stated in 1811 by Amedeo Avogadro. This number is 6.022 X 10^23. This law states and I qoute "equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties". An atomic mass is the average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element. These two things are connected to eachother because if you know the atomic mass of an atom then you can multiply it by Avogrado's number to find the atom's mass. So when you are assuming that Cl has a mass of 35.453 then you would need to multiply this number by 10^23 then divided by three so 15 grams would be approximatly be 4.17x 10^22?

Avogadro's number is a number that represents 6.022137 × 10^23 and is dimensionless:"One mole of anything is just Avogadro's number of that something or the number of atoms in a mole is called Avogadro's number." It relates to atomic mass because a mole contains almost precisely the relative atomic mass or molar mass of that substance(in grams). But, this is almost never valid for the atomic mass. If Cl mass is 35.453 then there are about 5.89 × 10^-23 atoms in 15g of Chlorine.

The Avogadro constant is defined as the ratio of the number of entities N in a sample to the amount of substance through the relationship. Both in the International System of units. This factor truly remained, the molar mass of our entity, the mass per amount of substance, to the mass of said entity.

Avogadros number is about 6.0221415 × 10^23. This relates to atomic mass because when the atomic mass of an element is multiplied by Avogadros number, then you get that elements mass. If Cl's mass is 35.453, then there are 5.639254722 x 10^23 in 15g

Avogadro's number ( NA ) is defined as a fundamental physical constant used to convert moles of a substance to a quantity of particles which make up that substance. The closest known approximation of its value is 6.0221415x10^23 mol-1 (with an uncertainty of 0.000 001 0x10^23).

Its most common application is in finding the number of atoms in n grams of an element having n atomic mass units.

Avogadro's number is the number of molecules in on mole. It is about 6.0221415 × 10^23. It relates to atomic mass because you use it to find the number of atoms in a certain amount of space by multiplying the atomic number. Since the atomic number of Cl is 35.435, we can figure out that in 15 grams of Chlorine there are 218 302.659 atoms.

Avogadro's number 6.0221415 × 10^23. He created this number because he wanted to group a bunch of molecules. Instead of saying a large number of molecules , becausse some are so small he created a number that people acccepted.They use this number to convert from macroscopic to microscopic or visaversa. They also call it mole. Which is the amount of 12 carbons in an area.

To be more precise, this number is expressed as 6.02214179 x 1023 mol-1. This is related to atomic mass because this constant is used to calculate the amount of atoms in a certain amount of space. There are exactly 2.36353333 x 6.0225 × 10 to the 23rd power atoms in 15 grams of chlorine, or 1.423 x 10 to the 24th power atoms.

Avogadro's number is a number representing the number of molecules in one mole which is equal to 6.0221415 × 10^23 Approx. 602,250,000,000,000,000,000,000. Avogadro's number and atomic mass is related because if you can find the atomic mass of a number then you can multiple it by Avogadro's number then you can find the atoms mass. If Cl mass is 35.453, their are 5.88920266 × 10-23 atoms in 15g.

ReplyDeleteAvogadro's number is the number of molecules in on mole. It relates to atomic mass because you use it to find the amount of atoms in a certain amount of space by multiplying the atomic number. Knowing the atomic number of Cl, 35.435, we can figure out that in 15g of Chlorine there are 218 302.659 atoms or molecules.

Avogadro's number is basically a representation of the ratio of entities, Or atoms and molecules, to the substance, wiki says substance is measured in mole which means nothing to me. The actual number is 6.0221415 x 10^23 or something like that. This is related to the mass of an atom or atomic mass is that if you multiply it by the really big Avogadro number, then you can find the atomic mass. Soooooooo if the mass of 1 chlorine atom is 35.453, then you can use Avogadro's number to fugure out that there are 5.89 x 10^23 (i rounded) atoms in 15g of chlorine. (Pretty Smart Huh?)

Avogrados number, by definition, is the number of molecules in a mole (represented as mol) of a substance. It is also equal to the number of atoms in 12g of Carbon-12. The exact number would be 6.022137 X 10^23, meaning that one mole is equal to approximately 6.02 X 10^23.

Avogrado's number relates to atomic mass because since atoms and molecules are so small that they cannot be counted by observing them,we use this indirect method to find out the number of atoms or molecules in an element/ compound.

To find how many atoms are in a given mass of a certain substance, we use the formula: given mass/molar mass X Avogrado's number. This means that in 15g of Chlorine there are 2.54794016 (aprox. 2.55) X 10^23 atoms.

Since atoms and molecules are so tiny, they cannot be counted by direct observation. One of the ways that they are counted is using Avogrado's number. Avogrado's number is the number of particles found in the mole of a substace. It is the number of atoms found in 12 grams of carbon-12. The number is approximatly 6.022137 x 10^23 particles per mole.It is related to atomic mass because the weight of an atom may be calculated back from the atomic weight by dividing it by 6.022137 x 10^23. If Cl mass is 35.453, there are approximatly 5.89 x 10^23 atoms in 15g of Chlorine.

The mole is defined as the quantity of a substance that contains the same number of “units” as the number of atoms in 12 grams of Carbon-12. This number can be represented by 6.02 x 10^23 and it is known as Avogrado’s number. In other words, Avogrado’s number is the quantity (or number) of atoms in precisely 12 grams of Carbon-12, which is 6.02 x 10^23. Avogrado’s number is directly related to atomic mass. Atomic mass is calculated by finding the weight (in grams) of 6.02 x 10^23 of an element. If Cl has a mass of 35.453, there are about 2.5 x 10^23 atoms in 15 grams of Chlorine.

Avogadro is famous for his quote, “Equal volumes of ideal or perfect gasses, at the same temperature and pressure, contain the same number of particles, or molecules.” This basically means that if any two gases are under the same conditions and have the same volume, they will have the same amount of molecules. This can be used to find the number of atoms in a specific volume of any "ideal or perfect" gas.

Avogrado's number is a law that was stated in 1811 by Amedeo Avogadro. This number is

6.022 X 10^23. This law states and I qoute "equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties". An atomic mass is the average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element. These two things are connected to eachother because if you know the atomic mass of an atom then you can multiply it by Avogrado's number to find the atom's mass. So when you are assuming that Cl has a mass of 35.453 then you would need to multiply this number by 10^23 then divided by three so 15 grams would be approximatly be 4.17x 10^22?

Avogadro's number is a number that represents 6.022137 × 10^23 and is dimensionless:"One mole of anything is just Avogadro's number of that something or the number of atoms in a mole is called Avogadro's number." It relates to atomic mass because a mole contains almost precisely the relative atomic mass or molar mass of that substance(in grams). But, this is almost never valid for the atomic mass. If Cl mass is 35.453 then there are about 5.89 × 10^-23 atoms in 15g of Chlorine.

The Avogadro constant is defined as the ratio of the number of entities N in a sample to the amount of substance through the relationship. Both in the International System of units. This factor truly remained, the molar mass of our entity, the mass per amount of substance, to the mass of said entity.

ReplyDeleteCl mass is 35.453, than 2.54794016 time 10^23 many atoms are there in 15 g of Chlorine.

Avogadros number is about 6.0221415 × 10^23. This relates to atomic mass because when the atomic mass of an element is multiplied by Avogadros number, then you get that elements mass. If Cl's mass is 35.453, then there are 5.639254722 x 10^23 in 15g

Avogadro's number ( NA ) is defined as a fundamental physical constant used to convert moles of a substance to a quantity of particles which make up that substance. The closest known approximation of its value is 6.0221415x10^23 mol-1 (with an uncertainty of 0.000 001 0x10^23).

Its most common application is in finding the number of atoms in n grams of an element having n atomic mass units.

Number of atoms of an element =

grams

------------ x Avagandros Number

atomic weight

( grams divided by atomic weight times Avagandros Number)

Number of atoms in 15 grams of chlorine =

15 ----------- x 6.022 141 5x1023

35.453

( 15 divided by 35.453 times Avagandors number)

Number of atoms of an element = moles (amount of a substance) x Avogadro's Number

Avogadro's number is the amount of atoms in 12 grams of Carbon-12. This number is also represented by a mole in the SI system.

23

The exact number is 6.0221415x 10 .

I haven't found a simple english explanation on how to use it to find atomic mass though.

Avogadro's number is the number of molecules in on mole. It is about 6.0221415 × 10^23. It relates to atomic mass because you use it to find the number of atoms in a certain amount of space by multiplying the atomic number. Since the atomic number of Cl is 35.435, we can figure out that in 15 grams of Chlorine there are 218 302.659 atoms.

Avogadro's number 6.0221415 × 10^23. He created this number because he wanted to group a bunch of molecules. Instead of saying a large number of molecules , becausse some are so small he created a number that people acccepted.They use this number to convert from macroscopic to microscopic or visaversa. They also call it mole. Which is the amount of 12 carbons in an area.
