Transcribed Image Text:A mixture of solid calcium oxide, CaO, and solid barium oxide, BaO, weighing 4.504 g is added to a 2.00 L flask containing
carbon dioxide, CO₂, at 30 °C. The CaO and BaO react completely with the carbon dioxide gas to form solid CaCO3 and
BaCO3, respectively. Calculate the moles of CO₂ consumed by the reaction if the initial pressure of CO₂ gas was 0.898 atm and
the final pressure of CO₂ gas is 0.313 atm.
moles of CO₂:
