Molar and molecular weight of SO4

• Molecular formula: SO4 or O4S
• Relative molecular weight of SO4: 96.0626
• Molar mass of SO4: 96.0626 g/mol (0.09606 kg/mol)

Calculation of the relative molecular and molar mass of SO4

• Mr[SO4] = Ar[O] * 4 + Ar[S] = 15.9994 * 4 + 32.065 = 96.0626
• Molar mass (kg/mol) = Mr[SO4] : 1000 = 96.0626 : 1000 = 0.09606 kg/mol

SO4: percent composition by element

• Oxygen (O) = 63.9976 : 96.0626 * 100 = 66.621 %
• Sulfur (S) = 32.065 : 96.0626 * 100 = 33.379 %
