ANSWER WITH FULL METHOD

just ignore if you don't know the answer ​

Answer 1

H2O2 + KMnO4 => 2KOH + 2MnO2 + 2O2

Molar mass of H2O2 = 34 g, which means in 100 g of solution, 34g of H2O2 are present

3.4g of the solution contains 0.x g of H2O2

e the weight of hydrogen peroxide as x/100 in 3 .4 gram. Since the equivalent weight of H2O2 is 17, the number of equivalence in this solution would be x/1700.

Equivalents in KMnO4 will be Nx/1000

x/1700 = Nx/1000
