Molar and molecular weight of O4SZn

• Molecular formula: O4SZn or ZnSO4
• Relative molecular weight of O4SZn: 161.4716
• Molar mass of O4SZn: 161.4716 g/mol (0.16147 kg/mol)

Calculation of the relative molecular and molar mass of O4SZn

• Mr[O4SZn] = Ar[O] * 4 + Ar[S] + Ar[Zn] = 15.9994 * 4 + 32.065 + 65.409 = 161.4716
• Molar mass (kg/mol) = Mr[O4SZn] : 1000 = 161.4716 : 1000 = 0.16147 kg/mol

O4SZn: percent composition by element

• Oxygen (O) = 63.9976 : 161.4716 * 100 = 39.634 %
• Sulfur (S) = 32.065 : 161.4716 * 100 = 19.858 %
• Zinc (Zn) = 65.409 : 161.4716 * 100 = 40.508 %
