The experimental enthalpy of dissolution of ammonium chloride were determined using another coffee-cup calorimeter. Water was first placed in the calorimeter and the known amount of ammonium chloride was placed in the calorimeter. Then, the final temperature was measured. Determine the experimental enthalpy of dissolution of ammonium chloride given the following data. Express your answers in kJ/mol and in 2 decimal places moles NH,Cl: 0.023 mol AT: -10.4°C mass of the solution: 51.2 g Ccal: 57.43 J/°C final temperature: 290.15K Cp of water: 4.184 J/g°C
