The equivalent weight of \(\mathrm{Fe}\) in \(\mathrm{Fe}_2 \mathrm{O}_3\) is
\(\left(\right.\) Atomic mass of \(\mathrm{Fe}=56 \mathrm{~g} \mathrm{~mol}^{-1}\) )
- A \(56.0\)
- B \(18.6\)
- C \(28.0\)
- D \(14.0\)
Answer & Solution
Correct Answer
(B) \(18.6\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{Fe}_2 \mathrm{O}_3\), the oxidation state of \(\mathrm{Fe}\) is +3 . It means one-third of \(\mathrm{Fe}\) mole is enough to combine with \(8 \mathrm{~g}\) of \(\mathrm{O}_2\). Therefore, the equivalent weight of iron in…
