Molar and molecular weight of CuCl

• Molecular formula: CuCl or ClCu
• Relative molecular weight of CuCl: 98.999
• Molar mass of CuCl: 98.999 g/mol (0.099 kg/mol)

Calculation of the relative molecular and molar mass of CuCl

• Mr[CuCl] = Ar[Cl] + Ar[Cu] = 35.453 + 63.546 = 98.999
• Molar mass (kg/mol) = Mr[CuCl] : 1000 = 98.999 : 1000 = 0.099 kg/mol

CuCl: percent composition by element

• Chlorine (Cl) = 35.453 : 98.999 * 100 = 35.811 %
• Copper (Cu) = 63.546 : 98.999 * 100 = 64.189 %
