Molar and molecular weight of NbBr5

• Relative molecular weight of NbBr5: 492.42638
• Molar mass of NbBr5: 492.42638 g/mol (0.49243 kg/mol)

Calculation of the relative molecular and molar mass of NbBr5

• Mr[NbBr5] = Ar[Nb] + Ar[Br] * 5 = 92.90638 + 79.904 * 5 = 492.42638
• Molar mass (kg/mol) = Mr[NbBr5] : 1000 = 492.42638 : 1000 = 0.49243 kg/mol

NbBr5: percent composition by element

• Niobium (Nb) = 92.90638 : 492.42638 * 100 = 18.867 %
• Bromine (Br) = 399.52 : 492.42638 * 100 = 81.133 %
