Molar and molecular weight of H3O4P

• Molecular formula: H3O4P or H3PO4
• Relative molecular weight of H3O4P: 97.995182
• Molar mass of H3O4P: 97.995182 g/mol (0.098 kg/mol)

Calculation of the relative molecular and molar mass of H3O4P

• Mr[H3O4P] = Ar[H] * 3 + Ar[O] * 4 + Ar[P] = 1.00794 * 3 + 15.9994 * 4 + 30.973762 = 97.995182
• Molar mass (kg/mol) = Mr[H3O4P] : 1000 = 97.995182 : 1000 = 0.098 kg/mol

H3O4P: percent composition by element

• Hydrogen (H) = 3.02382 : 97.995182 * 100 = 3.086 %
• Oxygen (O) = 63.9976 : 97.995182 * 100 = 65.307 %
• Phosphorus (P) = 30.973762 : 97.995182 * 100 = 31.607 %
