###### Question:

A coffee cup calorimeter was used to measure the heat of solution, the change in enthalpy that occurs when a solid dissolves in water. A 10.0 g sample of an ionic compound with a molar mass of 190.0 g/mol was added to a sample of deionized water to produce 60.0 grams of solution. After stirring and dissolving the solid, the temperature was found to change from 25.00 °C to 23.86 °C. Calculate the enthalpy of solution, AH coln, per mole of salt dissolved. Assume the specific heat of the solution is 4.06 J/(g:°C) and the heat capacity of the calorimeter is 7.00 J/ °C. Calculate the heat change experienced by the calorimeter contents, qcontents -
Calculate the heat change experienced by the calorimeter, qcal - 9cal = Calculate the heat change produced by the solution process, 9soln · Isoln =
Calculate AH soln , the enthalpy of solution for one mole of solid in kilojoules per mole. AH soln = kJ/mol
