Hi my dear friend,
Molecular mass. Relative molecular mass or molecular weight is the mass of a molecule. It is calculated as the sum of the relative atomic masses of each constituent element multiplied by the number of atoms of that element in the molecular formula.

The molar mass of a compound tells you the mass of 1 mole of that substance.
In other words, it tells you the number of grams per mole of a compound.
The units for molar mass are, therefore, grams/mole. .
.. The molecular mass - the mass of a molecule - is the sum of the masses of its atomic components.
