Magnetite, ${\mathrm{Fe}}_3{\mathrm{O}}_4$, can be reduced to iron by heating with carbon monoxide according to the equation:

${\mathrm{Fe}}_3{\mathrm{O}}_4+4\mathrm{CO}⟶3\mathrm{Fe}+4{\mathrm{CO}}_2$

Molar mass $\left(\mathrm{g} {\mathrm{mol}}^{-1}\right)$
${\mathrm{Fe}}_3{\mathrm{O}}_4$	232

What mass of ${\mathrm{Fe}}_3{\mathrm{O}}_4$ is required in order to obtain 5.0kg of iron if the process is 88% efficient?
