Question

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 separation of solute 19.5 kJ/mol

separation of solvent 20.8 kJ/mol

formation of solute-solvent interactions -83.7 kJ/mol solute

Calculate the enthalpy of solution in kilojoules per mole of solute. Enter your answer numerically in kilojoules per mole of solute.
