The Born-Haber cycle for KCl is evaluated with the following data:
${\mathrm{\Delta }}_{\mathrm{f}}{\mathrm{H}}^0\mathrm{for}\mathrm{KCl}=-436.7{\mathrm{KJmol}}^{-1};$
${\mathrm{\Delta }}_{\mathrm{sub}}{\mathrm{H}}^0\mathrm{for}\mathrm{K}=89.5{\mathrm{KJmol}}^{-1};$
${\mathrm{\Delta }}_{\mathrm{ionization}}{\mathrm{H}}^0\mathrm{for}\mathrm{K}=419.0{\mathrm{KJmol}}^{-1};$
${\mathrm{\Delta }}_{\mathrm{electron}\mathrm{gain}\mathrm{enthalpy}}{\mathrm{H}}^0\mathrm{for}\mathrm{Cl}{}_{\left(\mathrm{g}\right)}=-348.6{\mathrm{KJmol}}^{-1};$
${\mathrm{\Delta }}_{\mathrm{bond}\mathrm{dissiociation}\mathrm{energy}}{\mathrm{H}}^0\mathrm{for}\mathrm{Cl}{}_2=243.0{\mathrm{KJmol}}^{-1};$
The magnitude of lattice enthalpy of KCl in KJmol-1  is ___ (Nearest integer)
