Question

Quizplus · Accepted Answer

In a 5% NaCl solution, the percentage refers to the amount of sodium chloride in the total solution. Therefore, there are 5 grams of sodium chloride for every 100 mL of total solution, including both water and salt. Choice A refers only to the amount of sodium chloride dissolved in the water, not the total solution. Choices C and E are incorrect as water cannot be the solute in a solution with NaCl. Choice D is also incorrect as it implies that the amount of sodium chloride in water and in the total solution is different, which is not the case.
