Question 62

Iron is extracted from iron(III) oxide in a blast furnace by reaction with carbon monoxide.

The balanced equation for this reaction is

\text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2

Starting with 24.0 g of iron(III) oxide, calculate the maximum mass of iron that could be formed in this reaction. (relative atomic masses: $O=16.0\text{O} = 16.0$ , $Fe=56.0\text{Fe} = 56.0$ )

You must show your working.
