Molar and molecular weight of NiCl2

• Molecular formula: NiCl2 or Cl2Ni
• Relative molecular weight of NiCl2: 129.5994
• Molar mass of NiCl2: 129.5994 g/mol (0.1296 kg/mol)

Calculation of the relative molecular and molar mass of NiCl2

• Mr[NiCl2] = Ar[Cl] * 2 + Ar[Ni] = 35.453 * 2 + 58.6934 = 129.5994
• Molar mass (kg/mol) = Mr[NiCl2] : 1000 = 129.5994 : 1000 = 0.1296 kg/mol

NiCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 129.5994 * 100 = 54.712 %
• Nickel (Ni) = 58.6934 : 129.5994 * 100 = 45.288 %
