 Question 12470: how much water must be evaporated from 32 ounces of a 4% salt solution to produce a 6% salt solution?Answer by Earlsdon(6287)   (Show Source): You can put this solution on YOUR website!Let's see, 32 oz of 4% salt solution is 96% water and 6% salt solution is 94% water. Since we are not removing any salt, the question can be rephrased: How much water must be evaporated from 32 oz of 96% water solution to produce a 94% water solution? Change the percentages to decimals. 94% = 0.94, 96% = 0.96, 100% = 1 The equation is now in terms of water rather than salt: Subtract 30.08 from both sides. Add x to both sides. Divide both sides by 0.06 So, 10.67 oz of water must be evaporated. This is one third of the original 32 oz. of solution.
