What mass (in grams) of calcium carbonate is needed to react completely with 73 mL of 0.10 M HCl according to 2HCl + CaCO3 --> CaCl2 + H20 + CO2?
This problem is worked the same way as the BaCl2/Na2SO4/BaSO4 problem. If you need extra help on stoichiometry, here is an example problem I've posted. Just follow the steps.
