Molar and molecular weight of CCu2O3

• Molecular formula: CCu2O3 or Cu2CO3
• Relative molecular weight of CCu2O3: 187.1009
• Molar mass of CCu2O3: 187.1009 g/mol (0.1871 kg/mol)

Calculation of the relative molecular and molar mass of CCu2O3

• Mr[CCu2O3] = Ar[C] + Ar[Cu] * 2 + Ar[O] * 3 = 12.0107 + 63.546 * 2 + 15.9994 * 3 = 187.1009
• Molar mass (kg/mol) = Mr[CCu2O3] : 1000 = 187.1009 : 1000 = 0.1871 kg/mol

CCu2O3: percent composition by element

• Carbon (C) = 12.0107 : 187.1009 * 100 = 6.419 %
• Copper (Cu) = 127.092 : 187.1009 * 100 = 67.927 %
• Oxygen (O) = 47.9982 : 187.1009 * 100 = 25.654 %
