Molar and molecular weight of H2O3

• Molecular formula: H2O3 or HOOOH
• Relative molecular weight of H2O3: 50.01408
• Molar mass of H2O3: 50.01408 g/mol (0.05001 kg/mol)

Calculation of the relative molecular and molar mass of H2O3

• Mr[H2O3] = Ar[H] * 2 + Ar[O] * 3 = 1.00794 * 2 + 15.9994 * 3 = 50.01408
• Molar mass (kg/mol) = Mr[H2O3] : 1000 = 50.01408 : 1000 = 0.05001 kg/mol

H2O3: percent composition by element

• Hydrogen (H) = 2.01588 : 50.01408 * 100 = 4.031 %
• Oxygen (O) = 47.9982 : 50.01408 * 100 = 95.969 %
