Lattice energy is the energy of interaction between the particles in a solid. For an ionic crystal, the LE can be compared between different substances by using Coulomb's law:
kq1q2/r2
where q1 and q2 is the charge on the cation and anion and r is the distance between the substances (think radii of ions). The higher the LE, the tougher it is to separate the ions and the tougher it is to dissolve the ions.

ok, so to break the IMF's we use the lattice energy...but the solute-solvent interactions have to be grater than solvent-solvent and solute-solute.
