Molar gas volume

A sample of calcium carbonate, CaCO₃, is heated strongly and decomposes according to the equation:

$CaCO_3(s) \rightarrow CaO(s) + CO_2(g)$.

If 5.00 g of CaCO₃ ($M_r = 100$) is completely decomposed, what volume of CO₂ is produced at room temperature and pressure (RTP)? (1 mol of gas occupies 24.0 dm³ at RTP.)
