A hypothetical solution forms between a solid and a liquid. The values of the thermodynamic quantities involved in the process are shown in the following table. Action Enthalpy 16.5 kJ/mol separation of solute separation of solvent 23.8 kJ/mol formation of solute-solvent interactions -81.7 kJ/mol solute Calculate the enthalpy of solution in kilojoules per mole of solute Enter your answer numerically in kilojoules per mole of solute.

A4.00 m solution of KCI was prepared using 1.00 kg of water at 25.0°C. Once the solid had all dissolved the temperature of the solution was 12.3°C. Calculate the heat of solution, AHolm. of KCL Assume that the specific heat of the solution is identical to that of water, 4.18 J/(g-°C). Express your answer numerically in kilojoules per mole. ▸ View Available Hint(s) 197) ΑΣΦ kJ/mol 27
