Question

A chemist is using 354 milliliters of a solution of acid and water. If 15.8% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer 1

There is 55.9 mL of acid in the solution.

Explanation:

We have:

V = 354 mL

%(a): concentration of acid = 15.8 %

Hence, we can find the number of milliliters of acid as follows:

`x = V*\%_(a)`

`x = 354*(15.8)/(100) = 55.9 mL`

Therefore, there is 55.9 mL of acid in the solution.

I hope it helps you!
