What would be the best way to measure the moles of a reaction between calcium carbonate and sulfuric acid?

Question

I know that I could measure the moles before and the moles after by doing the mass by the molar mass but Is there a better way to do this.

Answer 1

The reaction is CaCO₃(aq) + H₂SO₄(aq) ==> CaSO₄(aq) + H₂O(l) + CO₂(g)

Since CO₂ gas is generated, you could measure the CO₂ that is evolved during the reaction and from the stoichiometry of the balanced equation, you could then determine moles of reactants that were used. The volume of CO₂ can easily be determined using a gas syringe attached to the reaction vessel. Using the ideal gas law, the volume is then converted to moles.
