Calculation of the relative molecular and molar mass of C3H3N3O3
• Mr[C3H3N3O3] = Ar[C] * 3 + Ar[H] * 3 + Ar[N] * 3 + Ar[O] * 3 = 12.0107 * 3 + 1.00794 * 3 + 14.0067 * 3 + 15.9994 * 3 = 129.07422
• Molar mass (kg/mol) = Mr[C3H3N3O3] : 1000 = 129.07422 : 1000 = 0.12907 kg/mol
C3H3N3O3: percent composition by element
• Carbon (C) = 36.0321 : 129.07422 * 100 = 27.916 %
• Hydrogen (H) = 3.02382 : 129.07422 * 100 = 2.343 %
• Nitrogen (N) = 42.0201 : 129.07422 * 100 = 32.555 %
• Oxygen (O) = 47.9982 : 129.07422 * 100 = 37.187 %
