Molecular Mass
The molecular mass of a substance is the number of times the molecule of the substance is heavier than one-twelth the mass of an atom of carbon -12. Or, the molecular mass is equal to the sum of its atomic masses of all the atoms present in one molecule of a substance. For eg: Water (H2O)

Gram Molecular Mass
The molecular mass of a substance expressed in grams is the gram molecular mass. For eg: Molecular mass of oxygen = 32u
∴ Gram molecular mass of oxygen = 32 g
the atomic mass of lithium ions
6.941 u
