Calcium carbonate (limestone, CaCO₃) dissolves in hydrochloric acid, producing water and carbon dioxide as shown in the following unbalanced net ionic equation:

Suppose 5.0 g of CaCO₃ is added to 700. mL of 0.10 M HCl. What is the maximum mass of CO₂ that could be formed? What would the final concentration of Ca²⁺ ions be? (Assume that the final solution volume is still 700 mL.)
