A student wants to measure the heat of crystallization of sodium acetate trihydrate. The student takes 50 g of sodium acetate trihydrate and dissolves it in 100 ml of water at 70°C. The solution is then allowed to cool to 20°C, during which the sodium acetate trihydrate crystallizes out. The student measures the temperature change during this process and finds that the temperature drops to 45°C. What is the heat of crystallization of sodium acetate trihydrate in kJ/mol?
