The eq. wt. of

\mathrm{Fe}{\mathrm{C}_2}{\mathrm{O}_4}

in ,

\mathrm{Fe}{\mathrm{C}_2}{\mathrm{O}_4} \to \mathrm{F}{\mathrm{e}^{3 + }} + 2\mathrm{C}{\mathrm{O}_2}\mathrm{is}:

View answer and explanation

Correct option: B

mol. wt./3

Option B (mol. wt./3) is correct because the equivalent weight is the molecular weight divided by the change in oxidation number, which is 3 in this case.
