The salt calcium bromide is soluble in water. When 1.48 g of CaBr2 is dissolved in 112.00 g of water, the temperature of the solution increases from 25.00 to 26.56 °C. Based on this observation, calculate the enthalpy of dissolution of CaBr2 (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.
