2:19 Experimental datat at atmospheric pressure for the mutual solubilities of 3-pentanone (comp. 1) and water (comp. 2) are shown below, in mass %. 0/C 40.3 50.0 60.1 w % 1 in 2 3.86 3.62 3.43 w % 2 in 1 2.49 2.81 2.98 Estimate the partial molar enthalpy of solution of water in 3-pentanone and 3-pentanone in water at 0 = 50 C. The partial molar enthalpy of solu- tion is defined as the enthalpy change for transferring a mole of solute from its own pure phase to the solution phase at saturation.
