Molar and molecular weight of Au2O3

• Relative molecular weight of Au2O3: 441.931338
• Molar mass of Au2O3: 441.931338 g/mol (0.44193 kg/mol)

Calculation of the relative molecular and molar mass of Au2O3

• Mr[Au2O3] = Ar[Au] * 2 + Ar[O] * 3 = 196.966569 * 2 + 15.9994 * 3 = 441.931338
• Molar mass (kg/mol) = Mr[Au2O3] : 1000 = 441.931338 : 1000 = 0.44193 kg/mol

Au2O3: percent composition by element
