The enthalpy of vaporization of chloroform (CHCl3) is 29.2 kJ mol-1 at its normal boiling point 61.2 Celsius. what is the standard change in entropy for vaporization of chloroform at its normal boiling point?
Answer I got was 29.2/334.2 = 0.0873. (CORRECT?)
You forgot to convert it. The correct answer is 87.3 J/(mol×k).
