To find the molecular weight of a substance, it is necessary to add the atomic masses of the individual elements that make up the molecule.

Mr (Ca) = 40 g / mol

Mr (O) = 16 g / mol

Mr (N) = 14 g / mol

Mr (H) = 1 g / mol

Mr (CaO) = 40 + 16 = 56 g / mol

Mr (Ca3N2) = 40 * 3 + 14 * 2 = 120 + 28 = 148 g / mol

Mr (Ca (OH) 2) = 40 + 2 * (16 + 1) = 40 + 34 = 74 g / mol
