Molar and molecular weight of MoO2

• Relative molecular weight of MoO2: 127.9388
• Molar mass of MoO2: 127.9388 g/mol (0.12794 kg/mol)

Calculation of the relative molecular and molar mass of MoO2

• Mr[MoO2] = Ar[Mo] + Ar[O] * 2 = 95.94 + 15.9994 * 2 = 127.9388
• Molar mass (kg/mol) = Mr[MoO2] : 1000 = 127.9388 : 1000 = 0.12794 kg/mol

MoO2: percent composition by element

• Molybdenum (Mo) = 95.94 : 127.9388 * 100 = 74.989 %
• Oxygen (O) = 31.9988 : 127.9388 * 100 = 25.011 %
