The salt cesium sulfate is soluble in water. When 22.7 g of Cs2SO4 is dissolved in 120.00 g of water, the temperature of the solution decreases from 25.00 to 22.96 °C. Based on this observation, calculate the enthalpy of dissolution of Cs2SO4 (in kJ/mol). Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.

Question

The salt cesium sulfate is soluble in water. When 22.7 g of Cs2SO4 is dissolved in 120.00 g of water, the temperature of the solution decreases from 25.00 to 22.96 °C. Based on this observation, calculate the enthalpy of dissolution of Cs2SO4 (in kJ/mol).

Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.
