The eq. wt. of

\mathrm{F}{\mathrm{e}_3}{\mathrm{O}_4}

in ,

\mathrm{F}{\mathrm{e}_3}{\mathrm{O}_4} + \mathrm{KMn}{\mathrm{O}_4} \to \mathrm{F}{\mathrm{e}_2}{\mathrm{O}_3} + \mathrm{Mn}{\mathrm{O}_2}

is:

View answer and explanation

Correct option: B

M

Option B (M) is correct because the n-factor for

\mathrm{F}{\mathrm{e}_3}{\mathrm{O}_4}

in the given reaction is 1, hence the equivalent weight is equal to the molecular weight.
