Determining Molarity from Sodium Chloride Dissolution

Consider a solution made by dissolving 4 grams of sodium chloride (NaCl) in 100 mL of water. Sodium chloride is an ionic compound, which dissociates completely into sodium (Na⁺) and chloride (Cl^-) ions when it dissolves. Each ion contributes to the total concentration of solute particles in the solution. Based on this information, answer the following question:

What is the total concentration of solute particles in the solution in terms of molarity?
