Question
A solution is prepared by dissolving 25.0 g of NaCl (formula wt = 58.5) in enough water to make 350 mL of solution. The molarity of the solution is
Correct Answer
Option A is the correct answer.
Detailed Explanation
Moles NaCl = 25.0/58.5 = 0.4274 mol. Volume = 0.350 L. Molarity = 0.4274/0.350 = 1.22 M.
Hint
Molarity = moles of solute / liters of solution.
