the amount of iron deposited in ${\mathrm{FeSO}}_4$ and ${\mathrm{Fe}}_2{\left({\mathrm{SO}}_4\right)}_3$ are equal.

the amount of iron deposited in ${\mathrm{FeSO}}_4$ is 1.5 times of the amount of iron deposited in $\mathrm{Fe}{\left({\mathrm{NO}}_3\right)}_3$.

the amount of iron deposited in ${\mathrm{Fe}}_2{\left({\mathrm{SO}}_4\right)}_3$ and $\mathrm{Fe}{\left({\mathrm{NO}}_3\right)}_3$ are equal

the same amount of gas is evolved in all three cases at the anode.
