Ferric oxide can be obtained by oxidation of $\mathrm{FeO} :$

$4\mathrm{FeO}+{\mathrm{O}}_2⟶2{\mathrm{Fe}}_2{\mathrm{O}}_3$   ..(i)

The ${\mathrm{O}}_2$ gas required can be prepared by the following reaction.

$2{\mathrm{SO}}_3⟶2{\mathrm{SO}}_2+{\mathrm{O}}_2\left(g\right)$

What is the maximum amount of ${\mathrm{Fe}}_2{\mathrm{O}}_3$ that can be produced by $144\mathrm{gFeO}$ and $160{\mathrm{gSO}}_3$? [Atomic mass of $\mathrm{Fe} = 56$]
