A calorimeter was used to measure the heat change when an ionic compound dissolves in water. The final mass of the contents of the calorimeter was 50.80 g and the change in temperature was 2.86 degree C. Calculate the heat change of the calorimeter contents, given that its specific heat is 4.10 J/(g degree C).Calculate the heat change of the calorimeter, given that its heat capacity is 7.9 J/ degree C. Calculate the heat change of the solution process.
