The salt barium chloride is solublein water. When 10.2 gof BaCl2 is dissolvedin 117.00 g of water, the temperature ofthe solution increasesfrom 25.00 to 26.79 °C.Based on this observation, calculate the enthalpy of dissolutionof BaCl2 (in kJ/mol).
Assume that the specific heat of the solution is 4.184 J/g °C andthat the heat absorbed by the calorimeter is negligible.
?Hdissolution
= kJ/mol
