Molar and molecular weight of Bi2O3

• Relative molecular weight of Bi2O3: 465.959
• Molar mass of Bi2O3: 465.959 g/mol (0.46596 kg/mol)

Calculation of the relative molecular and molar mass of Bi2O3

• Mr[Bi2O3] = Ar[Bi] * 2 + Ar[O] * 3 = 208.9804 * 2 + 15.9994 * 3 = 465.959
• Molar mass (kg/mol) = Mr[Bi2O3] : 1000 = 465.959 : 1000 = 0.46596 kg/mol

Bi2O3: percent composition by element
