# 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 $F {e}_{2} {O}_{3} \left(s\right) + 3 C O \left(g\right) \to 2 F e \left(s\right) + 3 C {O}_{2} \left(g\right)$.

1117 grams of iron

#### Explanation:

As can be seen from the chemical equation, each mole of $F {e}_{2} C {O}_{3}$ needs 3 moles of $C O$. If 30 moles of $C O$ are used, only 10 moles of $F {e}_{2} C {O}_{3}$ can be reduced, generating 20 moles of $F e$, corresponding to 1117 grams of iron.
