Answer 1

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 6.02214076×10^23 molecules oratoms of that substance. As an example, the molar mass of water: M(H2O) ≈18.015 g/mol.
