Question 24

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

FeO(s)+CO(g)→Fe(s)+CO2(g) \text{FeO(s)} + \text{CO(g)} \rightarrow \text{Fe(s)} + \text{CO}_2\text{(g)} FeO(s)+CO(g)→Fe(s)+CO2​(g)

Calculate the mass of carbon monoxide, in kg\text{kg}kg, needed to react exactly with 18 kg18\text{ kg}18 kg of iron(II) oxide.

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