Calculate the $\Delta {\mathrm{H}}_{\text{vaporization }}\left[{\mathrm{CH}}_3\mathrm{COOH}(\ell )\right]$ in $\mathrm{kJ}/\mathrm{mol}$

Given data:

$\Delta {\mathrm{H}}_{solution}[\mathrm{KF}\cdot {\mathrm{CH}}_3\mathrm{COOH}(\mathrm{s})]$ in glacial acetic acid = $-3kJ/mol$

$\Delta {\mathrm{H}}_{solution}[\mathrm{KF}(\mathrm{s})]$ in glacial acetic acid = $35kJ/mol$

The strength of H-bond between ${\mathrm{F}}^{-}$(g) and ${\mathrm{CH}}_3\mathrm{COOH}(\mathrm{g})$ = $+46kJ/mol$

$\Delta \mathrm{H}[\mathrm{KF}\cdot {\mathrm{CH}}_3\mathrm{COOH}(\mathrm{s})\to {\mathrm{K}}^{+}(\mathrm{g})+{\mathrm{CH}}_3\mathrm{COOH}\cdot {\mathrm{F}}^{-}(\mathrm{g})]$ = $+734kJ/mol$

Lattice Enthalpy of $\mathrm{KF}(\mathrm{s})$ = $+797kJ/mol$
