A solution of hydrogen peroxide, H2O2, is titrated with a solution of potassium permanganate, KMnO4. The reaction is 5H2O2(aq) + 2KMnO4(aq) + 3H2SO4(aq) → 5O2(g) + 2MnSO4(aq) + K2SO4(aq) + 8H2O(l) It requires 51.7 mL of 0.145 M KMnO4 to titrate 20.0g of the solution of the hdrogen peroxide. What is the mass percentage of H2O2 in the solution?
