Each compound has a different molar mass.
Liquid sodium chloride is a conductor but not the best.
Sodium chloride is a compound with the chemical formula NaCl. As a mineral sodium chloride is called halite.
Sodium chloride (NaCl) is an inorganic salt (halide).
Sodium chloride is an ionic salt.
Refined sodium chloride is a chemical compound formed only from NaCl crystals.

Table salt is best classified as an ionic compound. It is composed of equal amounts of the chemical elements Sodium and Chlorine.
I suppose that the best method is a repeated crystallization/recrystallization process.
