Suppose you have a calorimeter that contains 100.0 grams of water at an initial temperature of 25 C. A salt (2.19 g, 0.020 moles) is dissolved in the water, and the final temperature is 29 C. Calculate the standard heat of solution (on a per mole basis). Was the dissolution exothermic or endothermic?
