Molar and molecular weight of VBr3

• Relative molecular weight of VBr3: 290.6535
• Molar mass of VBr3: 290.6535 g/mol (0.29065 kg/mol)

Calculation of the relative molecular and molar mass of VBr3

• Mr[VBr3] = Ar[V] + Ar[Br] * 3 = 50.9415 + 79.904 * 3 = 290.6535
• Molar mass (kg/mol) = Mr[VBr3] : 1000 = 290.6535 : 1000 = 0.29065 kg/mol

VBr3: percent composition by element

• Vanadium (V) = 50.9415 : 290.6535 * 100 = 17.527 %
• Bromine (Br) = 239.712 : 290.6535 * 100 = 82.473 %
