Be sure to answer all parts. The active agent in many hair bleaches is hydrogen peroxide. The amount of H₂O₂ in 14.1-g of hair bleach was determined by titration with a standard potassium permanganate solution: 2 MnO4 (aq) +5 H,O,(aq) +6 H*(aq) → 5 0,(g) + 2 Mn→+(aq) +8 H,O(D) (a) For the titration, how many moles of MnO4 were required if 37.9 mL of 0.189 M KMnO4 was needed to reach the end point? Write your answer to the correct number of significant figures. Enter your answer in scientific notation. x 10 mol MnO4 (b) How many moles of H₂O₂ were present in the 14.1 g sample of bleach? Write your answer to the correct number of significant figures. mol H₂O₂
