A 4.10 −g sample of a mixture of CaO and BaO is placed in a
1.00-L vessel containing CO2 gas at a pressure of 735 torr and a
temperature of 26 ∘C. The CO2 reacts with the CaO and BaO, forming
CaCO3 and BaCO3. When the reaction is complete, the pressure of the
remaining CO2 is 155 torr .
Calculate the number of moles of CO2 that have reacted.
Calculate the mass percentage of CaO in the mixture.

A mixture of CaO(s) and BaO(s) weighing 5.14 g is added to a
1.50 L container containing carbon dioxide gas at 750.2 torr and
30.2ºC. The oxides react with CO2 to form the metal carbonate, and
at the completion of the reaction, the pressure of CO2 is 230.7
torr. What was the mass of calcium oxide in the original
mixture?
