Answer:First to calculate number of moles of KMnO4 required to oxidize completely 2.70 g of oxallic acid in acidic medium
molecular weight of
Number of moles of oxalic acid=
=0.0214 g
5 moles of oxalic acid is oxidized by 2 moles of KMnO4
So 0.021 moles of oxalic acid is oxidized by moles of KMnO4=0.00857
And to calculate volume of 0.05 M KMnO4 solution is
0.05 moles of KMnO4 are contained in 1000 ml of the solution
and then 0.00857 moles of KMnO4 are contained
=171.42 ml
