3. The heat of the solution of a solid sample was determined using a coffee cup calorimeter that contains 250ml of water initially at 25C. As the sample is dissolved in the water, the temperature of the water decreased to 11C. What is the heat of the solution of the sample? Assume that the density of water is 1.00g/ml and that the coffee cup is a good insulator. Is the process endothermic or exothermic?
