Molar and molecular weight of Cl2Cu

• Molecular formula: Cl2Cu or CuCl2
• Relative molecular weight of Cl2Cu: 134.452
• Molar mass of Cl2Cu: 134.452 g/mol (0.13445 kg/mol)

Calculation of the relative molecular and molar mass of Cl2Cu

• Mr[Cl2Cu] = Ar[Cl] * 2 + Ar[Cu] = 35.453 * 2 + 63.546 = 134.452
• Molar mass (kg/mol) = Mr[Cl2Cu] : 1000 = 134.452 : 1000 = 0.13445 kg/mol

Cl2Cu: percent composition by element

• Chlorine (Cl) = 70.906 : 134.452 * 100 = 52.737 %
• Copper (Cu) = 63.546 : 134.452 * 100 = 47.263 %
