Molar and molecular weight of H4NO3

• Molecular formula: H4NO3 or NH4O3
• Relative molecular weight of H4NO3: 66.03666
• Molar mass of H4NO3: 66.03666 g/mol (0.06604 kg/mol)

Calculation of the relative molecular and molar mass of H4NO3

• Mr[H4NO3] = Ar[H] * 4 + Ar[N] + Ar[O] * 3 = 1.00794 * 4 + 14.0067 + 15.9994 * 3 = 66.03666
• Molar mass (kg/mol) = Mr[H4NO3] : 1000 = 66.03666 : 1000 = 0.06604 kg/mol

H4NO3: percent composition by element

• Hydrogen (H) = 4.03176 : 66.03666 * 100 = 6.105 %
• Nitrogen (N) = 14.0067 : 66.03666 * 100 = 21.21 %
• Oxygen (O) = 47.9982 : 66.03666 * 100 = 72.684 %
