Molar and molecular weight of NiI2

• Relative molecular weight of NiI2: 312.50234
• Molar mass of NiI2: 312.50234 g/mol (0.3125 kg/mol)

Calculation of the relative molecular and molar mass of NiI2

• Mr[NiI2] = Ar[Ni] + Ar[I] * 2 = 58.6934 + 126.90447 * 2 = 312.50234
• Molar mass (kg/mol) = Mr[NiI2] : 1000 = 312.50234 : 1000 = 0.3125 kg/mol

NiI2: percent composition by element

• Nickel (Ni) = 58.6934 : 312.50234 * 100 = 18.782 %
• Iodine (I) = 253.80894 : 312.50234 * 100 = 81.218 %
