They also call it mole.

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?<br /><br /><br />Citations:<br />Goldberg, D.

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. <br /><br />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.<br /><br />Baker, Joanne 50 Physics Ideas You Really Need To Know London Quercus Publishing Plc 2007<br /><br />Hein, Morris Foundations of College Chemistry Alternate Thirteenth Edition <br /> <br />http://books.google.com/books?id=-XfMFmoqs2gC&pg=RA1-PA123&lpg=RA1-PA123&dq=what+is+avogadro's+number+how+does+it+relate+atomic+mass&source=bl&ots=LHhUK8Xp7c&sig=8bpWAYNIxlri7hVnVeK4mymNGDE&hl=en&ei=ZDmZTOGZGIK8lQf80ZA9&sa=X&oi=book_result&ct=result&resnum=8&ved=0CDcQ6AEwBw#v=onepage&q=what%20is%20avogadro's%20number%20how%20does%20it%20relate%20atomic%20mass&f=falseUnknownhttps://www.blogger.com/profile/11802647285792909643noreply@blogger.comtag:blogger.com,1999:blog-4297839691694588645.post-37253418947442815912010-09-21T19:28:26.124-07:002010-09-21T19:28:26.124-07:00Enmanuel Espinales

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.<br /><br />http://www.wisegeek.com/what-is-avogadros-number.htmUnknownhttps://www.blogger.com/profile/03732608669270124093noreply@blogger.comtag:blogger.com,1999:blog-4297839691694588645.post-77461217611631593882010-09-21T17:40:57.841-07:002010-09-21T17:40:57.841-07:00Broderick Schwinghammer

Avogadro’s numb...Broderick Schwinghammer <br />Period 7<br /><br />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. <br /><br />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.<br /><br />Baker, Joanne 50 Physics Ideas You Really Need To Know London Quercus Publishing Plc 2007<br /><br />Hein, Morris Foundations of College Chemistry Alternate Thirteenth Edition <br /> <br />http://books.google.com/books?id=-XfMFmoqs2gC&pg=RA1-PA123&lpg=RA1-PA123&dq=what+is+avogadro's+number+how+does+it+relate+atomic+mass&source=bl&ots=LHhUK8Xp7c&sig=8bpWAYNIxlri7hVnVeK4mymNGDE&hl=en&ei=ZDmZTOGZGIK8lQf80ZA9&sa=X&oi=book_result&ct=result&resnum=8&ved=0CDcQ6AEwBw#v=onepage&q=what%20is%20avogadro's%20number%20how%20does%20it%20relate%20atomic%20mass&f=falseUnknownhttps://www.blogger.com/profile/11802647285792909643noreply@blogger.comtag:blogger.com,1999:blog-4297839691694588645.post-41077273550923144882010-09-21T17:37:15.382-07:002010-09-21T17:37:15.382-07:00Avogadro's number is the number of molecules i...Avogadro's number is the number of molecules in one mole of a substance. It is equal to 6.022 x 10^23. The Avogadro's number relates to the mass of a mole of a substance to the mass of a single molecule. For example, the molar mass of carbon is defined as the mass in grams that is numerically equal to the average atomic weight. What this means <br />is that 1 mole of carbon is equal to 12.01 grams carbon. 12.01 is the mass of carbon that contains 6.022 x 1023 carbon atoms which is Avogadro's number. Using Avogadro's number we can find the molar mass of any element. In 15 g of Cl there are 4.67 x 10^23 atoms.<br /> <br /><br /><br /><br />http://www.chem1.com/acad/webtext/intro/MOL.htmlUnknownhttps://www.blogger.com/profile/14875919415203031831noreply@blogger.com
