Molar and molecular weight of VO2

• Molecular formula: VO2 or O2V
• Relative molecular weight of VO2: 82.9403
• Molar mass of VO2: 82.9403 g/mol (0.08294 kg/mol)

Calculation of the relative molecular and molar mass of VO2

• Mr[VO2] = Ar[O] * 2 + Ar[V] = 15.9994 * 2 + 50.9415 = 82.9403
• Molar mass (kg/mol) = Mr[VO2] : 1000 = 82.9403 : 1000 = 0.08294 kg/mol

VO2: percent composition by element

• Oxygen (O) = 31.9988 : 82.9403 * 100 = 38.581 %
• Vanadium (V) = 50.9415 : 82.9403 * 100 = 61.419 %
