Question

what do you mean by molecular mass​

Answer 1

Molecular mass is the mass of a molecule that is equal to the sum of the masses of all the atoms contained in the molecule.

In simple terms, molar mass of a substance is the total weight of that substance (in either kilogram or gram) for one mole of that substance. That is, the weight of a substance for 6.02214076×1023 molecules or atoms of that substance. As an example, the molar mass of water: M(H2O) ≈ 18.015 g/mol.
