Question

A mouthwash contains 22.5% (v/v) alcohol. If the bottle of mouthwash contains 355 mL, what is the volume, in milliliters , of alcohol?

Please solve in simple steps in order for me to understand :) Thank you!

Answer 1

Answer #1

Given:

(v/v)% = 22.5 %

Volume of solution = 355 mL

Use:

(v/v)% = volume of alcohol * 100 / volume of solution

22.5 = volume of alcohol * 100 / 355

volume of alcohol = 79.9 mL

Answer: 79.9 mL
