A solution of ${\mathrm{Fe}}_2{\left({\mathrm{SO}}_4\right)}_3$ is electrolyzed for '$\mathrm{x}$' min with a current of $1.5 \mathrm{A}$ to deposit $0.3482 \mathrm{g}$ of $\mathrm{Fe}$. The value of $\mathrm{x}$ is - [nearest integer]

Given : $1 \mathrm{F}=96500 {\mathrm{Cmol}}^{-1}$. Atomic mass of $\mathrm{Fe}=56 {\mathrm{gmol}}^{-1}$
