The boiling point elevation constant for toluene is \( 3.32 \mathrm{~K} \) \( \mathrm{kg} \mathrm{mol}^{-1} \), the normal boiling point of toluene is \( 110.7^{\circ} \mathrm{C} \). The enthalpy of vaporization of toluene would by nearly (A) \( 17.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(B) \( 34.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(C) \( 51.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(D) \( 68.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
