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 180.0 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 degree C to 23.99 degree C. Calculate the enthalpy of solution, delta H per mole of salt dissolved. Assume the specific heat of the solution is 4.07 J/(g degree C) and the heat capacity of the calorimeter is 3.70 J/degree C. Calculate the heat change experienced by the calorimeter contents, qcontents. Number I Calculate the heat change experienced by the calorimeter, qscl Calculate the heat change produced by the Number solution process, q. Calculate delta H solution,the enthalpy of solution for Number one mole of solid in kJ/mol.
