For the decolorisation of one mole of KMnO4 in acidic medium the number of moles of H2O2 required is

From balanced equation:KMnO4      H2O22 moles → 5 moles1 mole  → ? moles⇒ i.e., 2 moles of KMnO4 decolonised (or) reduced by 5-moles of H2O2where as 1 mole of KMnO4 is decolonised by ___moles of H2O2
