Molar and molecular weight of NiS2

• Relative molecular weight of NiS2: 122.8234
• Molar mass of NiS2: 122.8234 g/mol (0.12282 kg/mol)

Calculation of the relative molecular and molar mass of NiS2

• Mr[NiS2] = Ar[Ni] + Ar[S] * 2 = 58.6934 + 32.065 * 2 = 122.8234
• Molar mass (kg/mol) = Mr[NiS2] : 1000 = 122.8234 : 1000 = 0.12282 kg/mol

NiS2: percent composition by element

• Nickel (Ni) = 58.6934 : 122.8234 * 100 = 47.787 %
• Sulfur (S) = 64.13 : 122.8234 * 100 = 52.213 %
