The salt sodium perchlorate is soluble in water. When 8.44 g of NaClO4 is dissolved in 104.00 g of water, the temperature of the solution decreases from 25.00 to 22.73 °C. Based on this observation, calculate the enthalpy of dissolution of NaClO4 (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.
