The active agent in many hair bleaches is hydrogen peroxide. The amount of H_2O_2 in 14.9-g of hair bleach was determined by titration with a standard potassium permanganate solution: 2 MnO_4^- (aq) + 5 H_2O_2(aq) + 6 H+(aq) rightarrow 5 O_2(g) + 2 Mn^2+(aq) + 8 H_2O(I) For the titration, how many moles of MnO_4 were required if 36.7 mL of 0.131 M KMnO_4 was needed to reach the end point? Write your answer to the correct number of significant...

Please Help!
When 0.1009 g of sodium cyanide is dissolved in solution, it takes 19.22 mL of a potassium permanganate solution to reach the endpoint of the titration. Using the balanced chemical equation provided, determine the molarity of the potassium permanganate. You will be doing a similar reaction in the laboratory this week. (Remember: the mole ratio of MnO_4^- to KMnO_4 is 1:1 and the mole ratio of CN^- to NaCN is 1:1) H2O (l) + 2 MnO_4^- (aq) +...
