moles of NaCl per liter of solution.

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.

  • For [NaCl] is a symbol for: moles of NaCl per liter of solution.
Answer 2
Answer:

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=(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.

ThusNaCl represents moles of NaCl per liter of solution.
