mole is defined as the amount of a substance which contains the same number of elementary entities (e.g. atoms, molecules, ions, electrons, photons) as atoms in 0.012 kilograms of carbon-12. Gram atomic mass is the mass (in grams) of one mole of atoms in a monatomic element. It is numerically equal to the relative atomic mass (or atomic weight) in grams. Gram molecular mass is the mass (in grams) numerically equal to the molecular weight of a substance or the sum of all the atomic masses in its molecular formula.
