Molar and molecular weight of CuO

• Relative molecular weight of CuO: 79.5454
• Molar mass of CuO: 79.5454 g/mol (0.07955 kg/mol)

Calculation of the relative molecular and molar mass of CuO

• Mr[CuO] = Ar[Cu] + Ar[O] = 63.546 + 15.9994 = 79.5454
• Molar mass (kg/mol) = Mr[CuO] : 1000 = 79.5454 : 1000 = 0.07955 kg/mol

CuO: percent composition by element

• Copper (Cu) = 63.546 : 79.5454 * 100 = 79.886 %
• Oxygen (O) = 15.9994 : 79.5454 * 100 = 20.114 %
