Molar and molecular weight of NH4OH

• Molecular formula: NH4OH or H5NO
• Relative molecular weight of NH4OH: 35.0458
• Molar mass of NH4OH: 35.0458 g/mol (0.03505 kg/mol)

Calculation of the relative molecular and molar mass of NH4OH

• Mr[NH4OH] = Ar[H] * 5 + Ar[N] + Ar[O] = 1.00794 * 5 + 14.0067 + 15.9994 = 35.0458
• Molar mass (kg/mol) = Mr[NH4OH] : 1000 = 35.0458 : 1000 = 0.03505 kg/mol

NH4OH: percent composition by element

• Hydrogen (H) = 5.0397 : 35.0458 * 100 = 14.38 %
• Nitrogen (N) = 14.0067 : 35.0458 * 100 = 39.967 %
• Oxygen (O) = 15.9994 : 35.0458 * 100 = 45.653 %
