25.0 g of a limestone sample that is 80% CaCO₃ by mass (the rest is unreactive) is treated with 200 mL of 1.5 M HCl. CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l) + CO₂(g) What volume of CO₂ is released? Take the molar volume of a gas under the conditions of the experiment as 22.7 L mol⁻¹. (Ca = 40 u, C = 12 u, O = 16 u)
