Acoffee 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 160.0 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 23.92 ∘c . calculate the enthalpy of solution, δ , per mole of salt dissolved. assume the specific heat of the solution is 4.07 j/(g⋅∘c ) and the heat capacity of the calorimeter is 5.30 j/ ∘c .
