The active agent in many hair bleaches is hydrogen peroxide. The amount of hydrogen peroxide in 17.0 g of hair bleach was determined by titration with a standard potassium permanganate solution.
2 MnO4-(aq) + 5 H2O2(aq) + 6 H+(aq) 5 O2(g) + 2 Mn2+(aq) + 8 H2O(l)
what is the mass % of H2O2 in this equation the givens r .402g of H2O2, 4.73X10^-3 moles of MnO4 and 1.18X10^-2 moles of H2O2

the only other part of the question is How many moles of MnO4- were required for the titration if 43.4 mL of 0.109 M KMnO4 was needed to reach the end point?

I thought that I saw this problem before, and maybe you repost it since no one has answered it.
Well, I think that your problem is wrong. Please check the given data. Specifically, you have not given enough information on MnO4-
