Practice Problem 2: A 5.15 g sample of a salt with a molar mass of 115.23 g/mol is added to a calorimeter containing 54.13 g of deionized water. The initial temperature of the water is 21.53°C, the final temperature of the solution is 18.87°C. What is the molar enthalpy of dissolution in kJ/molt Assume the specific heat of the solution is the same as pure water, 4.184 J/g°C. Remember that the mass of the solution is equal to the mass of the water plus the mass of the salt.
