Molar and molecular weight of H2O4S

• Molecular formula: H2O4S or H2SO4
• Relative molecular weight of H2O4S: 98.07848
• Molar mass of H2O4S: 98.07848 g/mol (0.09808 kg/mol)

Calculation of the relative molecular and molar mass of H2O4S

• Mr[H2O4S] = Ar[H] * 2 + Ar[O] * 4 + Ar[S] = 1.00794 * 2 + 15.9994 * 4 + 32.065 = 98.07848
• Molar mass (kg/mol) = Mr[H2O4S] : 1000 = 98.07848 : 1000 = 0.09808 kg/mol

H2O4S: percent composition by element

• Hydrogen (H) = 2.01588 : 98.07848 * 100 = 2.055 %
• Oxygen (O) = 63.9976 : 98.07848 * 100 = 65.251 %
• Sulfur (S) = 32.065 : 98.07848 * 100 = 32.693 %
