The salt cesium chloride is soluble in water. When 9.32 g CsCl is dissolved in 116,00 g water, the temperature of the solution decreases from 25.00 °C to 23.09 °C. Based on this observation, calculate the dissolution enthalpy, Adiss H. of CSCL Assume that the specific heat capacity of the solution is 4.184 J g'oc and that the energy transfer to the calorimeter is negligible.

Although each ion in a sodium chloride crystal has six nearest neighbors, the value of the lattice energy for NaCl(s), 1.28 aJ per formula unit, is only about one and a half times the magnitude of the coulombic energy per NaCl ion pair of 0.816 aJ. Why do you think the vaue of the energy for NaCl(s) isn't about six times that of the coulombic energy per ion pair?
