Molar and molecular weight of Nb2O3

• Relative molecular weight of Nb2O3: 233.81096
• Molar mass of Nb2O3: 233.81096 g/mol (0.23381 kg/mol)

Calculation of the relative molecular and molar mass of Nb2O3

• Mr[Nb2O3] = Ar[Nb] * 2 + Ar[O] * 3 = 92.90638 * 2 + 15.9994 * 3 = 233.81096
• Molar mass (kg/mol) = Mr[Nb2O3] : 1000 = 233.81096 : 1000 = 0.23381 kg/mol

Nb2O3: percent composition by element

• Niobium (Nb) = 185.81276 : 233.81096 * 100 = 79.471 %
• Oxygen (O) = 47.9982 : 233.81096 * 100 = 20.529 %
