What is the Molar Mass of MgCl2 in Grams per Mole

Answer: Molar mass is simply calculated by the sum of the atomic mass of all the atoms present in the molecule. The molecular mass unit is in grams per mole (g/mol). The molar mass of MgCl₂ can be computed as the sum of the molar mass of Mg i.e 24.3 g/mol and the molar mass of two atoms of chlorine i.e 2×35.5 = 71g/mol.

Hence the molar mass of MgCl₂ is  24.3 +71 =95.3 grams per mole (i.e. 95.3 g/mol).
