A 8.65 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72 °C. After the salt has completely dissolved, the temperature of the solution is 28.54 °C. If 3.20 x 10³ J of heat was gained by the solution, what is the total heat for the dissolution reaction of the 8.65 g of salt?
