question
An experiment is performed to measure the mass percent of (s) in eggshells. Five different samples of (s) of known mass react with an excess of 2.0 M (aq) in identical sealed, 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 experimental data are used to create the calibration line below. <image 1> The experiment is repeated with an eggshell sample, and the experimental data are recorded in the table below. <image 2> Another sample of eggshell reacts completely with 4.0 mL of an (aq) solution of unknown concentration. If the reaction produced 0.095 atm of gas, the concentration of the (aq) solution was at least

An experiment is performed to measure the mass percent of CaCO₃(s) in eggshells. Five different samples of CaCO₃(s) of known mass react with an excess of 2.0 M HCl(aq) in identical sealed, 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.

Original LaTeX notation
An experiment is performed to measure the mass percent of $CaCO_3$(s) in eggshells. Five different samples of $CaCO_3$(s) of known mass react with an excess of 2.0 M $HCl$(aq) in identical sealed, 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 experimental data are used to create the calibration line below. <image 1> The experiment is repeated with an eggshell sample, and the experimental data are recorded in the table below. <image 2> Another sample of eggshell reacts completely with 4.0 mL of an $HCl$(aq) solution of unknown concentration.
