A student placed a mixture of BaO and CaO in a 1.46 L flask containing carbon dioxide gas at 35.0 degrees celsius and 746 mmHg. After the reactions were complete, she found that the CO2 pressure had dropped to 272 mmHg. How many moles of CO2 were consumed in the reactions? Assume volumes of the solids are negligible.
