A solution of hydrogen peroxide, H2O2 , is titrated with potassium permanganate, KMnO4 , according to the following equation:

5 H2O2 + 2 KMnO4+ 3H2SO4 -> 5O2 + 2 MnSO4 +8H2O + K2SO4
It requires 6.40mL of a 0.063M solution of KMnO4 to titrate 10.

Yes.

0.0064 L x 0.063M = 0.0004032 moles KMnO4
(5/2) x 0.0004032 = 0.001008 moles of H2O2 in 10 mL
0.001008 / 0.010 = 0.
