Answer 2

Answer: moles of $NaCl$ per liter of solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n= moles of solute

$V_s$ = volume of solution in L

Square brackets represents the concentration of a substance i.e. amount of solute dissolved per liter of the solution.

Thus $NaCl$ represents moles of $NaCl$ per liter of solution.
