First, we find out how much salt is in the solution. Let’s take 250 g of solution for 100%. We can make a proportion:
250 g – 100%
X g – 2.5%.
Let’s solve this proportion:
100 * X = 250 * 2.5;
100 * X = 625;
X = 6.25 (g) – salts in solution.
250 – 6.25 = 243.75 (g) – water in solution.
Answer: 243.75 grams of water in a solution.
