Quizplus · Accepted Answer

To make a solution with a concentration of 10.00 grams per liter, the student needs to dissolve 10.00 grams of sodium chloride in enough water to make the total volume of the solution 1 liter. Since the sodium chloride itself takes up some volume, the amount of water needed will be slightly less than 1 liter, approximately 0.992 liters, making the total solution volume 1 liter.
