Question

how many ounces of water evaporated from 100 oz of a 12% salt solution to produce a 16% salt solution? oz

Explanation:

Step1: Find the amount of salt

The initial solution is 100 oz and 12% salt. So the amount of salt is $100\times0.12 = 12$ oz.

Step2: Let the final amount of solution be $x$ oz

Since the amount of salt remains the same during evaporation and the final solution is 16% salt, we have the equation $0.16x=12$. Solving for $x$, we get $x=\frac{12}{0.16}=75$ oz.

Step3: Calculate the amount of water evaporated

The initial solution was 100 oz and the final is 75 oz. So the amount of water evaporated is $100 - 75=25$ oz.

Answer:

25
