The volume of

#### Explanation:

Let the volume of acetic acid

Then, the volume of water is

We write the material balance equation with respect to the component acetic acid

Solving this equation,

Do you mean "vinegar in water" or do you mean "acetic acid in water"?

#### Explanation:

If you want to make a 30% solution of acetic acid in water, the calculation is trivial: Total volume of solution = 500 ml. % by volume of acetic acid = 30%, therefore volume of acetic acid required =

However, a "30% vinegar in water" solution is entirely different, as vinegar is only 4 - 5 % acetic acid. So if you wanted to create the equivalent of a 30% vinegar in water solution using acetic acid and water, you would need to use approximately:

Please note that whilst acetic acid is a component of vinegar, acetic acid and vinegar are NOT the same thing!
