Question 24

The reduction of solid iron(II) oxide by carbon monoxide gas is represented by the following chemical equation:

\text{FeO(s)} + \text{CO(g)} \rightarrow \text{Fe(s)} + \text{CO}_2\text{(g)}

Calculate the mass of carbon monoxide, in $kg\text{kg}$ , needed to react exactly with $kg18\text{ kg}$ of iron(II) oxide.

[Relative atomic masses ( $A_r$ ): $C=12\text{C} = 12$ , $O=16\text{O} = 16$ , $Fe=56\text{Fe} = 56$ ]
