Answer 1

Answer: moles of
`NaCl` per liter of solution

Step-by-step explanation:

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

`Molarity=(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.

Answer 2

moles of NaCl per liter of solution.

Step-by-step explanation:

• [NaCl] is an expression of the concentration of NaCl.

• If the concentration is the molarity;

Molarity can be defined as the no. of moles of solute dissolved per a 1.0 L of the solution.
