Molar and molecular weight of NbI5

• Relative molecular weight of NbI5: 727.42873
• Molar mass of NbI5: 727.42873 g/mol (0.72743 kg/mol)

Calculation of the relative molecular and molar mass of NbI5

• Mr[NbI5] = Ar[Nb] + Ar[I] * 5 = 92.90638 + 126.90447 * 5 = 727.42873
• Molar mass (kg/mol) = Mr[NbI5] : 1000 = 727.42873 : 1000 = 0.72743 kg/mol

NbI5: percent composition by element

• Niobium (Nb) = 92.90638 : 727.42873 * 100 = 12.772 %
• Iodine (I) = 634.52235 : 727.42873 * 100 = 87.228 %
