Consider the dissolution of 2.50 grams of salt xy in 75.0 ml of water within a calorimeter. the temperature of the water decreased by 0.93 oc. the heat capacity of the calorimeter is 42.2 j/oc. the density of the water (and the solution) is 1.00 g/ml. the specific heat capacity of the solution is 4.184 j/goc. calculate the enthalpy change for dissolving this salt on a energy per mass basis (units of j/g).
