Chapter 9, Problem 119CP

The heat of vaporization of water at the normal boiling point, $\text{373}\text{.2 K}$ , is $\text{40}\text{.66 kJ/mol}$ . The specific heat capacity of liquid water is $\text{4}{\text{.184 J K}}^{\text{-1}}{\text{ g}}^{\text{-1}}$ and of gaseous water is $\text{2}{\text{.02 J K}}^{\text{-1}}{\text{ g}}^{\text{-1}}$ . Assume that these values are independent of temperature. What is the heat of vaporization of water at $\text{298}\text{.2 K}$ ? Does this result agree with Appendix $4$ data?
