Calculation of the relative molecular and molar mass of C21H28ClNO2

• Mr[C21H28ClNO2] = Ar[C] * 21 + Ar[H] * 28 + Ar[Cl] + Ar[N] + Ar[O] * 2 = 12.0107 * 21 + 1.00794 * 28 + 35.453 + 14.0067 + 15.9994 * 2 = 361.90552
• Molar mass (kg/mol) = Mr[C21H28ClNO2] : 1000 = 361.90552 : 1000 = 0.36191 kg/mol
