1 mole of `Fe^(2+)` ions are oxidised to `Fe^(3+)` ions with the help of ( in acidic medium)

One mole of \(Fe^{2+}\) ions are oxidized to \(Fe^{3+}\) ion with the help of "x" moles of \(KMnO_{4}\).The value of "5x" is

The non-stoichiometric compound Fe_0.94O is formed when some Fe^(+2) ions are replaced by Fe^(+3) ions. What is the percentage of Fe^(+3) ions in this ionic lattice ?
