A solution is prepared by dissolving 90 ml of hydrogen peroxide in enough water to make 3000 ml of solution. Identify the concentration of the hydrogen peroxide solution.

Given: Volume of solute = 90 ml

             Volume of solution = 3000 ml 

Solution:

Volume by volume percentage of a solution $= \frac{\mathrm{Volume} \mathrm{of} \mathrm{solute}}{\mathrm{Volume} \mathrm{of} \mathrm{solution}}\times 100$

                                                                                      $= \frac{90}{3000}\times 100$

                                                                                     $=\frac{9}{3}$

                                                                                    $=3\%$

 The volume by volume percentage of the given solution is 3%
