These types of questions can be easily solved without writing and balancing the chemical reaction. This method involves the use of the concept of gram equivalence.

It is given as N1V1 = N2V2

Or n factor 1 × no. Of moles 1 = n factor 2 × no.of moles 2

Here n factor of kmno4 in acidic medium is 5 and that of ferrous oxalate is 3.

Therefore we get the no of moles of know 4 required as 3/5

Dear student
Since in acidic medium according to the reaction 6moles of Kmno4 oxidizes 10 moles of ferrous oxalate
6moles kmno4=10 molesFeC2O4
3 moles. “=5 moles. “
3/5 moles= 1 mole
For 1 mole FeC2O4 3/5 or .6 mole kmno4 is required
