The two can be mixed in water, since the salt is soluble it will dissolve and the sand will remain. To separate it from the water use filter paper and a beaker.
As you can see, the unit of heat of vaporization is in kJ/mol, while the unit for entropy of vaporization is in J/mol·K. Since it is vaporization, this occurs at the boiling point. Thus, the formula would be:
Boiling Point = ΔHvap/ΔSvap
Make sure the units are consistent.
Boiling point = 55.5 kJ/mol * 1000 J/kJ / 148 J/mol·K = <em>375 K or 102°C</em>
