A mixture of `FeO and Fe_2 O_3` is completely reacted with `100mL` of `0.25M` acidified `KMnO_4` solution. The resulting solution was then treated with Zn dust which converted `Fe^(3+)` of the solution to `fe^(2+)`. The `Fe^(2=)` required `100mL` of `0.10MK_2 Cr_2O_7` solution. Find out the weight `% Fe_2O_3` in the mixture.
