Molar and molecular weight of HN3

• Relative molecular weight of HN3: 43.02804
• Molar mass of HN3: 43.02804 g/mol (0.04303 kg/mol)

Calculation of the relative molecular and molar mass of HN3

• Mr[HN3] = Ar[H] + Ar[N] * 3 = 1.00794 + 14.0067 * 3 = 43.02804
• Molar mass (kg/mol) = Mr[HN3] : 1000 = 43.02804 : 1000 = 0.04303 kg/mol

HN3: percent composition by element

• Hydrogen (H) = 1.00794 : 43.02804 * 100 = 2.343 %
• Nitrogen (N) = 42.0201 : 43.02804 * 100 = 97.657 %
