Molar and molecular weight of Cu2O3

• Relative molecular weight of Cu2O3: 175.0902
• Molar mass of Cu2O3: 175.0902 g/mol (0.17509 kg/mol)

Calculation of the relative molecular and molar mass of Cu2O3

• Mr[Cu2O3] = Ar[Cu] * 2 + Ar[O] * 3 = 63.546 * 2 + 15.9994 * 3 = 175.0902
• Molar mass (kg/mol) = Mr[Cu2O3] : 1000 = 175.0902 : 1000 = 0.17509 kg/mol

Cu2O3: percent composition by element

• Copper (Cu) = 127.092 : 175.0902 * 100 = 72.587 %
• Oxygen (O) = 47.9982 : 175.0902 * 100 = 27.413 %
