A 4.10 −g sample of a mixture of CaO and BaO is placed in a1.00-L vessel containing CO2 gas at a pressure of 735 torr and atemperature of 26 ∘C. The CO2 reacts with the CaO and BaO, formingCaCO3 and BaCO3. When the reaction is complete, the pressure of theremaining CO2 is 155 torr .
Calculate the number of moles of CO2 that have reacted.
Calculate the mass percentage of CaO in the mixture.
