Feb 11, 2012 · Since the molecules have different masses, if we take Avogadro’s Number of A and Avogadro’s Number of B (the same number of molecules), the total mass of each sample will be different. This total mass for one mole of A is the molar mass of A. So you get an equation: Mass of molecule * Avogadro’s Number = Molar Mass.
