How many grams of feo would be needed to make 234.2 grams of fe in the chemical reaction 4feo = fe3o4 + fe? show your work.

1,203.84 grams of FeO will be needed.

Explanation:

Moles of iron =

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:

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.
