In a laboratory experiment, a student reacts Na2CO3 (106 g mol−1) with HCl. Water displacement is used to measure the amount of CO2 produced (the gas over water is collect in a eudiometer). The total atmospheric pressure of the laboratory (760 mmHg), as well as the temperature of the water (22°C) and the volume of gas (502 mL) in the eudiometer, are known. Which additional data, if any, is needed to calculate the number of moles of CO2 gas collected during the experiment?
