WebA mole (abbreviated mol) is defined to be the amount of a substance that contains as many atoms or molecules as there are atoms in exactly 12 grams (0.012 kg) of carbon-12. The actual number of atoms or molecules in one mole is called Avogadro’s number ( NA ), in recognition of Italian scientist Amedeo Avogadro (1776–1856). WebFor example, theatomic mass of an oxygen atom is 16.00 amu; that means the molar massof an oxygen atom is 16.00 g/mol. Further, if you have 16.00 grams of oxygen atoms, you know from the definition of a mole that your sample contains 6.022 x 10 oxygen atoms. The concept of molar mass can also be applied to compounds.
