Acalorimeter was used to measure the heat change when an ionic compound dissolves in water. the final mass of the contents of the calorimeter was 50.70 g and the change in temperature was 2.00 °c. an insulated coffee cup is filled with a liquid and fully enclosed at the top, except for a small hole for a thermometer.

calculate the heat change of the calorimeter contents, given that its specific heat is 4.13 j/(g⋅°c.)
calculate the heat change of the calorimeter, given that its heat capacity is 7.0 j/°c.
calculate the heat change of the solution process.
