In \(\mathrm{Fe}_{0.96} \mathrm{O}, \mathrm{Fe}\) is present in +2 and +3 oxidation state, what is the mole fraction of \(\mathrm{Fe}^{2+}\) in the compound?
- A 12/25
- B 25/12
- C 1/12
- D 11/12
Answer & Solution
Correct Answer
(D) 11/12
Step-by-step Solution
Detailed explanation
Mole fraction is unit of amount of constituent, divided by total amount of all constituents in a mixture. Let us consider, there are ' \(x\) ' molecular fraction of \(\mathrm{Fe}^{2+}\) and \((0.96-x)\) molecular fraction of \(\mathrm{Fe}^{3+}\). Using charge conservation…
