Molar and molecular weight of ZnS

• Molecular formula: ZnS or SZn
• Relative molecular weight of ZnS: 97.474
• Molar mass of ZnS: 97.474 g/mol (0.09747 kg/mol)

Calculation of the relative molecular and molar mass of ZnS

• Mr[ZnS] = Ar[S] + Ar[Zn] = 32.065 + 65.409 = 97.474
• Molar mass (kg/mol) = Mr[ZnS] : 1000 = 97.474 : 1000 = 0.09747 kg/mol

ZnS: percent composition by element

• Sulfur (S) = 32.065 : 97.474 * 100 = 32.896 %
• Zinc (Zn) = 65.409 : 97.474 * 100 = 67.104 %
