Please help soon!! A chemist uses a calorimeter to determine the enthalpy of dissolving of a crystalline substance. She fills the calorimeter with 365 g of water. The water is at room temperature which is 20 C. She adds 92 grams of the solid and fastens the top. Once the materials has completely dissolves, she notes that the new temperature of the water is 9.3 C. Recall that the specific heat of water is 4.18 J/g °C. Using these data, calculate the enthalpy of dissolving (Hdissolving) of the solid in joules per gram (J/g). Work must be shown to earn credit.
