The calorimeter contains 330 g of water at 31°C. A sample of the substance with a mass of 115 grams is placed into the calorimeter. Once the substance has completely dissolved, the temperature of the water inside the calorimeter is 27.4°C. Recall that the specific heat of water is 4.18 J/g-°C. What is the enthalpy of fusion (Hf) of this sample in joules per gram?
