Some Notes on Homework #6

Problem 28
When calculating the percent error, compare your calculated enthalpy at 25 °C to the tabulated value at 0 °C (1189.5 J/g). Please ignore the fact that this tabulated value is not at the same temperature as your results. You do not need to rescale the tabulated value to 25 °C.

Problem 31-b
For this problem, assume that no phase changes occur - all components remain gases over all temperatures. Also assume that the heat capacity coefficients given in Appendix C.1 are valid over all temperatures. There is a typo in the problem, so don't worry if your answer seems off, just approach the problem the same way you've learned in class.
