The atomic mass of aluminum

WebAvogadro's number is the ratio of the mass of 12 grams of carbon-12 to the mass of 1 atom of carbon-12 measured in grams. Or, a little easier to understand, Avogadro's number is the ratio of 1 gram to 1 atomic mass unit but with the atomic mass unit expressed in grams. Thus, Avogadro's number has been measured to be 6.022141×10²³. Webatomic weight, also called relative atomic mass, ratio of the average mass of a chemical element’s atoms to some standard. Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. An isotope is one of two or more species of atoms of the same chemical element that have different atomic mass numbers …
