Calculate the mass of oxalic `(H_(2)C_(2)O_(4).2H_(2)O)` which can be oxidised to `CO_(2)` by `100 mL` of `MnO_(4)^(-)` (acidic) solution, `10 mL` of which are capable of oxidising `50.0 mL` of `1.0 m I^(-)` to `I_(2)`. Also calculate the weight of `FeC_(2)O_(4)` oxidised by same amount of `MnO_(4)^(-)`.

Answer» Correct Answer - `H_(2)C_(2) O_(4) = 31.5g, FeC_(2)O_(4) = 24g`
