Question

Quizplus · Accepted Answer

To find the amount of sodium chloride needed, we need to use the formula:
grams of sodium chloride = (volume of solution in L) x (% concentration/100)
So, for 3.5 L of a 0.90% NaCl solution:
grams of sodium chloride = (3.5 L) x (0.90/100) = 0.0315 kg = 31.5 g
Therefore, the best choice is A.
