Molar and molecular weight of ZnCl2

• Molecular formula: ZnCl2 or Cl2Zn
• Relative molecular weight of ZnCl2: 136.315
• Molar mass of ZnCl2: 136.315 g/mol (0.13632 kg/mol)

Calculation of the relative molecular and molar mass of ZnCl2

• Mr[ZnCl2] = Ar[Cl] * 2 + Ar[Zn] = 35.453 * 2 + 65.409 = 136.315
• Molar mass (kg/mol) = Mr[ZnCl2] : 1000 = 136.315 : 1000 = 0.13632 kg/mol

ZnCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 136.315 * 100 = 52.016 %
• Zinc (Zn) = 65.409 : 136.315 * 100 = 47.984 %
