A coffee cup calorimeter initially contains 140.g water at 22.7°C. 4.7g of a salt is added to the water and, after the salt dissolves, the final temperature is 28.0°C. Calculate the heat for the dissolving of the salt. Assume that the specific heat capacity of the solution is 4.2 J/g°C and that no heat is transferred to the surroundings or the calorimeter.
