Question

Iron is obtained commercially by the reaction of hematite `Fe_2O_3` with carbon monoxide. How many grams of iron is produced when 25.0 mol of hematite reacts with 30.0 mol of carbon monoxide?

The reaction is `Fe_2O_3(s) + 3CO(g) -> 2Fe(s) + 3CO_2(g)`.

Answer 1

1117 grams of iron

Explanation:

As can be seen from the chemical equation, each mole of `Fe_2CO_3` needs 3 moles of `CO`. If 30 moles of `CO` are used, only 10 moles of `Fe_2CO_3` can be reduced, generating 20 moles of `Fe`, corresponding to 1117 grams of iron.
