Question

Given a `10*mL` volume of `10%` solution, what volume is necessary to make a `1%` solution?

Answer 1

You don't take any volume.......

Explanation:

You simply take `10*mL` of the `10%` solution, and dilute this up to a `100*mL` volume with FRESH SOLVENT, i.e. a tenfold dilution that reduces the concentration to `1%`.
