How many coulombs are required for the following oxidation?
one mole of FeO to `Fe_(2)O_(3)`

Explanation

Conversion of FeO to `Fe_(2)O_(3)` involves the oxidation of `Fe^(2+)` to `Fe^(3+)` ions.
`underset(1" mole")(Fe^(2+)) to Fe^(3+) +underset("1 mole")(e^(-))`
`:. `1 mol of FeO requires 1 mole electrons or 96500 coulombs.
