In a calorimeter, 300 mL of 0.22 mol/L of calcium chloride is mixed with 200 mL of 0.33 mol/L of sodium phosphate. The initial temperature of the two solutions is 15.00°C. After mixing, the final temperature is 19.75°C. The density of the aqueous solutions is 1.02 g/mL, and its specific heat capacity is equal to that of water. Calculate the molar enthalpy of solution for NaCl. *Hint: you need to write a balanced chemical equation first
