Molar and molecular weight of C6H5NO2

• Relative molecular weight of C6H5NO2: 123.1094
• Molar mass of C6H5NO2: 123.1094 g/mol (0.12311 kg/mol)

Calculation of the relative molecular and molar mass of C6H5NO2

• Mr[C6H5NO2] = Ar[C] * 6 + Ar[H] * 5 + Ar[N] + Ar[O] * 2 = 12.0107 * 6 + 1.00794 * 5 + 14.0067 + 15.9994 * 2 = 123.1094
• Molar mass (kg/mol) = Mr[C6H5NO2] : 1000 = 123.1094 : 1000 = 0.12311 kg/mol
