Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, H2O2 a solution of hydrogen peroxide, , can be titrated against a solution of potassium permanganate, KMnO4. The following equation represents the reaction:

2KMnO4(aq) + H2O2(aq) + 3H2SO4 (aq) ---> O2(g) + 2MnSO4(aq) + K2SO4(aq) + 4H2O(l)

A certain amount of hydrogen peroxide was dissolved in 100 mL of water and then titrated with 1.68 M KMnO4. How much H2O2 was dissolved if the titration required 22.3mL of the KMnO4 solution?
