Molar and molecular weight of HgO4S

• Molecular formula: HgO4S or HgSO4
• Relative molecular weight of HgO4S: 296.6526
• Molar mass of HgO4S: 296.6526 g/mol (0.29665 kg/mol)

Calculation of the relative molecular and molar mass of HgO4S

• Mr[HgO4S] = Ar[Hg] + Ar[O] * 4 + Ar[S] = 200.59 + 15.9994 * 4 + 32.065 = 296.6526
• Molar mass (kg/mol) = Mr[HgO4S] : 1000 = 296.6526 : 1000 = 0.29665 kg/mol

HgO4S: percent composition by element

• Mercury (Hg) = 200.59 : 296.6526 * 100 = 67.618 %
• Oxygen (O) = 63.9976 : 296.6526 * 100 = 21.573 %
• Sulfur (S) = 32.065 : 296.6526 * 100 = 10.809 %
