Most of the information's required for solving this question is already given. Let us now focus on the problem in hand.

Grams/Molar Mass = Moles

Molarity = Moles/Liters

The above formulas are important for solving this problem.

Number of moles of Nacl = 87.75/58.44

= 1.50

Molarity = Number of moles of solute (here NaCl) / Volume of solution in Liters

Then

Volume of solution in Liters = Number of moles of solute (here NaCl) / Molarity

Volume of solution in Liters = 500/1500

= 0.333 M

The correct option among all the options that are given in the question is the first option or option "A".
