I am typing up a lab report for an introductory chemistry course. Basically we determined the entropy and enthalpy for the dissolution of potassium nitrate in water. The exp. values I found are close to each other but I'm supposed to compare to literature sources and I'm finding frustratingly that it takes more time to find a source than to type the paper. I can't find any handbooks that have this data and I don't know how to search the literature for this, it's just too specific because I have to have the thermodynamic data under similar conditions. The temperatures were in the 300-330 Kelvin Range, my exp. values are: 186.31 J/K*mol 48.244kJ/mol 186.04J/K*mol. 48.158kJ/mol. Any tips or help would be appreciated.
