Molar and molecular weight of MoCl2

• Relative molecular weight of MoCl2: 166.846
• Molar mass of MoCl2: 166.846 g/mol (0.16685 kg/mol)

Calculation of the relative molecular and molar mass of MoCl2

• Mr[MoCl2] = Ar[Mo] + Ar[Cl] * 2 = 95.94 + 35.453 * 2 = 166.846
• Molar mass (kg/mol) = Mr[MoCl2] : 1000 = 166.846 : 1000 = 0.16685 kg/mol

MoCl2: percent composition by element

• Molybdenum (Mo) = 95.94 : 166.846 * 100 = 57.502 %
• Chlorine (Cl) = 70.906 : 166.846 * 100 = 42.498 %
