In water solutions salt is dissociated: NaCl--------------Na+ + Cl-
The ions making up the solid salt disassociate in to Na+ and Cl-.
for the conductance of electricity freely moving ions and electrons are necessary. But in NaCl (in solid form) Na positive ion and Cl negative ion are held together by strong electrostatic force and there is no freely moving ion in NaCl (in solid state) therefore NaCl does not conduct electricity in solid form.

First- NaCl is not a molecular compound. Second you can't have fractioanl molecules. Do you mean Moles??
There are approximately 0.5 moles of NaCl in 29.22 grams. This would be 3.01 x 10^23 molecules of NaCl.
Sodium chloride is a solid, salt, inorganic compound; NaCl exist in the nature as the mineral halite. It is the most important food additive.
NaCl in frozen water NaCl in BaI2 (assuming BaI2 has the greater amount)
Sodium chloride (NaCl) is a solid.
No, solid NaCl cannot conduct an electrical current because ions are not free to move and carry the charge when in the solid state. Only in the molten or aqueous form can NaCl conduct electricity because the ions are mobile.
If you think to NaCl(s) the meaning is solid sodium chloride.
Solid sodium chloride is not an electrical conductor.
