FeSO_(4) undergoes decomposition as 2FeDO_(4)(s) rarr Fe_(2)O_(3)(s)+ SO_(2)(g) + SO_(3)(g) At 1 atm 273 K. If (7.6 gm) FeSO_(4) so taken then: The average molar mass of the gaseous mixture,

`n_("moles")` of `KMnO_(4)` required to oxidise `Fe^(2+)` to `Fe^(3+)` in acidic medium is 0.4

`n_("moles")` of `KMnO_(4)` required to oxidise `SO_(4)^(2-)` is `6//5`

`n_("moles")` of `KMnO_(4)` required to oxidise oxalate ion is 0.4

The total number of moles of `KMnO_(4)` required to completely oxidise the mixture is 0.8.

`(1)/(3)`

`(2)/(3)`

`(2)/(5)`

`(3)/(5)`
