A 6.13 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 3.15 x 10J of heat was gained by the solution, what
is the total heat for the dissolution reaction of the 6.13 g
of salt?
