Answer 2

Solid Sodium chloride exists in crystal form and the Lattice structure is F.C.C.

• Solid sodium chloride is an ionic compound.
• It exists in the form of Face Centered Cubic Lattice.
• The cations are present at the octahedral voids of the cube.
• The anions are present at the corners and at the face center of the cube.
• The ions are attracted by electrostatic force.
• One Na⁺ atom is surrounded by six Cl⁻ ions and one Cl⁻ ion is surrounded by six Na⁺ ions.

So, there is no individual existence of any NaCl molecule. The term Formula Mass is used for this instead of Molecular mass.
