When pure sodium hydroxide is dissolved in water, heat is evolved. In a laboratory experiment to measure the molar heat of solution of sodium hydroxide, the following procedure was followed. To a calorimeter containing 300g of water at 20.00 °C, 10.65 g of NaOH, also at 20.00 °C was added. The temperature change, which was monitored by a digital thermometer with negligible heat capacity, stopped when it reached a temperature of 28.50 degrees C. If the specific heat of the mixture is 4.184 J g-1 degree C1, and the small heat capacity of the calorimeter is ignored, what is the heat evolved, per mole of sodium hydroxide?
