The amount of charge in F (Faraday) required to obtain one mole of iron from Fe 3 O 4 is ______. (Round off the answer to the nearest integer)

Correct answer

0

Step-by-step solution

Fe 3 O 4 is a mixed oxide( Fe + 2 O   .   Fe + 3 2 O 3 ) The net change in oxidation can be calculated as follows, Fe 3 O 4 ⟶ + 8 e - 3 Fe For 3 moles of formation of iron, 8 moles of electrons are involved. One mole of electrons charge is called one Faraday. Charge for 1 mole Fe = 8 3 F = 2 . 67   F
