Answer:

59.7 mL

Explanation:

You want to know the amount of acid if 341 milliliters of a solution of acid and water is 17.5% acid.

Amount

The relation between base, percentage, and amount is ...

amount = percentage × base

In this relation, the percentage can be used directly on many calculators and spreadsheets. On others, it needs to be converted to a number or fraction before the multiplication can be done.

It can be useful to think of the % symbol as equivalent to "/100". Then we have ...

amount = 17.5/100 × 341 mL = 59.675 mL

There are about 59.7 mL of acid in the solution.
