4J3 7th Edition

For this problem, do we use the enthalpy and entropy of vaporization for NH3? I seem to be getting the incorrect answer and am not sure why.

Yes, you use the enthalpy and entropy given in the tables. Check your units. They usually give enthalpy in kJ and entropy in J, so it's possible you forgot to convert.
