The active ingredient in many hair bleaches is hydrogen peroxide, H2O2. The amount of hydrogen peroxide present can be determined by titration with a standard permanganate, MnO4, solution: 2 MnO4?(aq) + 5 H2O2(aq) + 6 H+(aq) ---> 5 O2 (g) + 2 Mn+2 (aq) + 8 H2O (l)Calculate the molarity of hydrogen peroxide if 28.75 mL of hydrogen peroxide produced 695 mL of oxygen gas at 0.950 atm and 315 K?
