Answer:

The correct option is (4)

Explanation:

Molarity (M) is generally defined as the number of moles of a solute per liter of the solution.

The formula for molarity (from the definition above) is

M = number of moles (n) ÷ volume (in liters or dm³)

The unit for molarity is mol/L or mol/dm³

From the above, it can be deduced that the molarity of an aqueous solution of common salt (NaCl) is the number of moles of NaCl per liter of the salt solution.
