A mouthwash contains 22.5% alchohol by mass. If the bottle of mouthwash contains 350 mL, what is the mass, in g, of alcohol?
Using the (m/v)%= Mass of solute (g)X100
Volume of solution(mL)
So far, I have:
Step 1. 22.5% alcohol= 22.5g alcohol
100 mL solution
Step 2. 350 mL mouth wash
and this is where I loose it.
Step one was given to me by my professor, however, I don't really know how to set up this problem ...... HELP!© BrainMass Inc. brainmass.com December 24, 2021, 5:13 pm ad1c9bdddf

If your mouthwash contains 22.5g alcohol in 100 mL solution then:
350 mL contain : 3.5 * 22.5 g = 78.75 g
because you have the 3.5 fold amount of mouthwash.
