Calculation of the relative molecular and molar mass of CH3C6H4NO2

Mr[CH3C6H4NO2] = Ar[C] * 7 + Ar[H] * 7 + Ar[N] + Ar[O] * 2 = 12.0107 * 7 + 1.00794 * 7 + 14.0067 + 15.9994 * 2 = 137.13598
Molar mass (kg/mol) = Mr[CH3C6H4NO2] : 1000 = 137.13598 : 1000 = 0.13714 kg/mol

CH3C6H4NO2: percent composition by element
