Molar and molecular weight of HNO

• Relative molecular weight of HNO: 31.01404
• Molar mass of HNO: 31.01404 g/mol (0.03101 kg/mol)

Calculation of the relative molecular and molar mass of HNO

• Mr[HNO] = Ar[H] + Ar[N] + Ar[O] = 1.00794 + 14.0067 + 15.9994 = 31.01404
• Molar mass (kg/mol) = Mr[HNO] : 1000 = 31.01404 : 1000 = 0.03101 kg/mol

HNO: percent composition by element

• Hydrogen (H) = 1.00794 : 31.01404 * 100 = 3.25 %
• Nitrogen (N) = 14.0067 : 31.01404 * 100 = 45.162 %
• Oxygen (O) = 15.9994 : 31.01404 * 100 = 51.588 %
