Here both Fe and oxalate ion undergo a change in oxidation number as shown below: The overall reaction is a 3e- change and hence the equivalent weight of FeC2O4 = (mol. wt/3) = (M/3)

Q. Equivalent weight of $F e C_{2} O_{4}$ in the change,
$F e C_{2} O_{4} ⟶ F e^{3 +} + C O_{2}$

M/3

M/6

M/2

M/1

Here both Fe and oxalate ion undergo a change in oxidation number as shown below :
The overall reaction is a $3 e^{-}$ change and hence the equivalent weight of $F e C_{2} O_{4} = \frac{m o l . wt}{3} = \frac{M}{3}$
