Question

How do I solve this problem? "vinegar is a 5% solution by volume of acetic acid. a 100 ml sample contains what volume of concentrated acid and what volume of water? show work."

Answer 1

`5` mL acetic acid
`95` mL water

Explanation:

Since `5%` of the vinegar, by volume, is acetic acid, and we have `100` mL of vinegar, we have `5` mL of vinegar.

Similarly, we have `100% - 5% = 95%` being water, so we have `95` mL of water.
