Question

How would you prepare 1.0L of an alcohol water solution that is 5.0% by volume alcohol?

Answer 1

Explanation:

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.
