Molar and molecular weight of VCl2

• Molecular formula: VCl2 or Cl2V
• Relative molecular weight of VCl2: 121.8475
• Molar mass of VCl2: 121.8475 g/mol (0.12185 kg/mol)

Calculation of the relative molecular and molar mass of VCl2

• Mr[VCl2] = Ar[Cl] * 2 + Ar[V] = 35.453 * 2 + 50.9415 = 121.8475
• Molar mass (kg/mol) = Mr[VCl2] : 1000 = 121.8475 : 1000 = 0.12185 kg/mol

VCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 121.8475 * 100 = 58.192 %
• Vanadium (V) = 50.9415 : 121.8475 * 100 = 41.808 %
