Molar and molecular weight of ZnS2O4

• Molecular formula: ZnS2O4 or O4S2Zn
• Relative molecular weight of ZnS2O4: 193.5366
• Molar mass of ZnS2O4: 193.5366 g/mol (0.19354 kg/mol)

Calculation of the relative molecular and molar mass of ZnS2O4

• Mr[ZnS2O4] = Ar[O] * 4 + Ar[S] * 2 + Ar[Zn] = 15.9994 * 4 + 32.065 * 2 + 65.409 = 193.5366
• Molar mass (kg/mol) = Mr[ZnS2O4] : 1000 = 193.5366 : 1000 = 0.19354 kg/mol

ZnS2O4: percent composition by element
