Ammonia (NH₃) shows basic character in aqueous solution:
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻. This is basic buffer, because contains hydroxide anions.
Ammonium chloride is salt and in water dissociate:
NH₄Cl → NH₄⁺ + Cl⁻.
Ammonium ion shows acidic character in aqueous solution::
NH₄⁺ + H₂O ⇄ NH₃ + H₃O⁺.
Ka = [NH₃] · [H₃O⁺] ÷ [NH₄⁺].

2.5 moles of sodium chloride is dissolved to make 0.050 liters of solution
Hitman42 [59]

The answer is:

the molarity = 50 moles/liters

The explanation:

when the molarity is = the number of moles / volume per liters.

and when the number of moles =2.5 moles

and the volume per liters = 0.05 L

so by substitution:

the molarity = 2.5moles/0.05L

                    = 50 moles /L
