WebAnswer (1 of 4): If we assume that each formula represents one mole of the compound, then the subscript for each element represents the number of moles of atoms of each element. 1 mol Al2S3 contains 2 mol Al atoms, 3 mol S atoms 1 mol NaNO3 contains 1 mol Na atoms, 1 mol N atoms, 3 mol O atoms ... WebOne molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen. We can calculate the mass of one molecule of carbon dioxide by adding together the masses of 1 atom of carbon and 2 atoms of oxygen. (8.3.1) 12.01 amu + 2 ( 16.00 amu) = 44.01 amu. The molecular mass of a compound is the mass of one molecule of that compound.
