Explanation:
Calculate moles of CO2 produced. If you are starting with one mole of CaCO3, then you might expect to produce one mole of CO2. But how many moles of CaCO3 did you determine in Step 1? That number is equal to the moles of CO2 produced. You could also use moles of HCl, divided by two, to calculate moles of CO2 produced.
Calculate volume of CO2 produced. The volume of one mole of CO2 produced is 24 dm^3 at room temperature and pressure. Alternatively, if your reaction took place at standard temperature and pressure (273 K, 1 atm), then the molar volume is 22.4 dm^3. Multiply the number of moles produced, calculated in Step 3, by the molar volume to calculate the volume of gas produced.
