Molar and molecular weight of HO3P

• Molecular formula: HO3P or HPO3
• Relative molecular weight of HO3P: 79.979902
• Molar mass of HO3P: 79.979902 g/mol (0.07998 kg/mol)

Calculation of the relative molecular and molar mass of HO3P

• Mr[HO3P] = Ar[H] + Ar[O] * 3 + Ar[P] = 1.00794 + 15.9994 * 3 + 30.973762 = 79.979902
• Molar mass (kg/mol) = Mr[HO3P] : 1000 = 79.979902 : 1000 = 0.07998 kg/mol

HO3P: percent composition by element

• Hydrogen (H) = 1.00794 : 79.979902 * 100 = 1.26 %
• Oxygen (O) = 47.9982 : 79.979902 * 100 = 60.013 %
• Phosphorus (P) = 30.973762 : 79.979902 * 100 = 38.727 %
