Question:

A 24.6-mL volume of a hydrochloric acid solution reacts completely with a solid sample of magnesium carbonate, producing 183 mL of CO2 that is collected over water at 24.0oC and 738 torr total pressure. The reaction is
2HCl(aq) + MgCO3(s) → CO2(g) + H2O(l) + MgCl2(aq)
What is the molarity of the HCl solution?
