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!
Homework Answers
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
