You perform an analysis as described in the procedure for this weeks experiment. The antacid tablet (Tums) is reacted with a solution of 25.0 mL 6.00 M HCl (aq). The principal ingredient in the antacid is calcium carbonate, CaCO3.

The reaction is: CaCO3 (s) + 2 HCl (aq) CaCl2 (aq) + H2O (l) + CO2 (g)

The label on the bottle says that each tablet contains 300 mg of elemental calcium (Ca).

1. How many moles of Ca are in each tablet?

2. How many mg of CaCO3 are in each tablet?

3. How many mol of CO2 are produced when the entire tablet reacts with excess HCl as above?

4. What mass of CO2 forms upon complete reaction?

5. What is the limiting reactant in the experiment?
