PLZ HELP ME!!!!

how much water must be evaporated from 32 ounces of a 4% salt solution to make an 8% salt solultion?

Answer 1

Answer:

16 ounces.

Step-by-step explanation:

An 8% solution is 2 times stronger than a 4% solution.

So in the 8% solution we will have 1/2 of the volume as a 4% , so 1/2 * 32

= 16 ounces of water must be evaporated.
