Compared to a 1.0-mole sample of nacl(s), a 1.0-mole sample of nacl(l) has a different number of
(1) ions
(2) empirical formula
(3) gram-formula mass
(4)electrical conductivity

(4)electrical conductivity

Explanation:

Given : 1.0 mole of and 1.0 mole of

1 mole of and 1.0 mole of ,. both have ions.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Thus both and have same empirical formula.

Both   and have same atoms ad thus have same gram formula mass.

Electrolyte is a substance which dissociates into ions when dissolved in water and thus is able to conduct electric current through them. Compounds in solid form does not conduct electricity due to the absence of free ions.

Bus as solid compounds do not dissociate, would not produce ions and thus have no electrical conductivity. will have electrical conductivity due to presence of ions in molten form.
