Molar and molecular weight of O3V2

• Molecular formula: O3V2 or V2O3
• Relative molecular weight of O3V2: 149.8812
• Molar mass of O3V2: 149.8812 g/mol (0.14988 kg/mol)

Calculation of the relative molecular and molar mass of O3V2

• Mr[O3V2] = Ar[O] * 3 + Ar[V] * 2 = 15.9994 * 3 + 50.9415 * 2 = 149.8812
• Molar mass (kg/mol) = Mr[O3V2] : 1000 = 149.8812 : 1000 = 0.14988 kg/mol

O3V2: percent composition by element

• Oxygen (O) = 47.9982 : 149.8812 * 100 = 32.024 %
• Vanadium (V) = 101.883 : 149.8812 * 100 = 67.976 %
