The active agent in many hair bleaches is hydrogen peroxide. The amount of H,O, in 14.6-g of hair bleach was determined by titration with a standard potassium permanganate solution: 2 MnO, (aq) + 5 H,O2(aq) + 6 H*(aq)→50½(g) + 2 Mn²*(aq) + 8 H,0(1) (a) For the titration, how many moles of MnO, were required if 46.1 mL of 0.154 M KMNO, 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 MnO, (b) How many moles of H,0, were present in the 14.6 g sample of bleach? Write your answer to the correct number of significant figures. mol H;O2
