Suppose 15.0 grams of solid sodium hydroxide solid at 20.5 oC is dropped into 120 grams of water in a container that has a heat capacity of 10.0 J/oC, temperature also 20.5 oC. A solution that has a density of 1.04 g/mL forms at a temperature of 38.0 oC. What is the heat of solution of sodium hydroxide solid in water in kJ/mole ?
