Molar gas volume

A student heats 5.00 g of calcium carbonate with excess hydrochloric acid. The reaction is:
$\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2$.
What is the maximum volume of $\text{CO}_2$ gas produced at room temperature and pressure? ($M_r(\text{CaCO}_3)=100$, molar gas volume = 24 dm³/mol)
