1,203.84 grams of FeO will be needed.

Explanation:

$4FeO\rightarrow Fe_3O_4 + Fe$

Moles of iron = $\frac{234.2 g}{56 g/mol}=4.18 mol$

According to reaction, 1 mol of iron is obtained from 4 moles of ferrous oxide.

Then 4.18 moles of iron will be obtained from:

$\frac{4}{1}\times 4.18 mol=16.72 mol$ of ferrous oxide

Mass of 16.72 moles of ferrous oxide:

16.72 mol × 72 g/mol = 1,203.84 g

1,203.84 grams of FeO will be needed.
