Molar and molecular weight of Yb2O3

• Molecular formula: Yb2O3 or O3Yb2
• Relative molecular weight of Yb2O3: 394.0782
• Molar mass of Yb2O3: 394.0782 g/mol (0.39408 kg/mol)

Calculation of the relative molecular and molar mass of Yb2O3

• Mr[Yb2O3] = Ar[O] * 3 + Ar[Yb] * 2 = 15.9994 * 3 + 173.04 * 2 = 394.0782
• Molar mass (kg/mol) = Mr[Yb2O3] : 1000 = 394.0782 : 1000 = 0.39408 kg/mol

Yb2O3: percent composition by element

• Oxygen (O) = 47.9982 : 394.0782 * 100 = 12.18 %
• Ytterbium (Yb) = 346.08 : 394.0782 * 100 = 87.82 %
