Molar and molecular weight of HgS

• Relative molecular weight of HgS: 232.655
• Molar mass of HgS: 232.655 g/mol (0.23266 kg/mol)

Calculation of the relative molecular and molar mass of HgS

• Mr[HgS] = Ar[Hg] + Ar[S] = 200.59 + 32.065 = 232.655
• Molar mass (kg/mol) = Mr[HgS] : 1000 = 232.655 : 1000 = 0.23266 kg/mol

HgS: percent composition by element

• Mercury (Hg) = 200.59 : 232.655 * 100 = 86.218 %
• Sulfur (S) = 32.065 : 232.655 * 100 = 13.782 %
