A coffee cup calorimeter initially contains 135g of water at 22.0oC. Calcium chloride (21.0g) at the same temperature is added to the water and after the CaCl2 dissolves the final temperature 46.0 degrees C. Calculate the molar enthalpy change for dissolving the salt in KJ/mol. Assume the solution has a heat capacity of 4.184 J/C g and assume no heat is lost to the surrounding or the calorimeter.
