An experiment is performed to measure the mass percent of CaCO, (s) in eggshells. Five different samples of
Cacos (s) of known mass remer with an excess of 2.0 M HCl(aq) in identical scaled, rigid reaction vessels.
The pressure of the gas produced is measured with a pressure gauge attached to the reaction vessel. Since the
reaction is exothermic, the reaction system is cooled to its original temperature before the pressure is recorded. The
