A chemist weighed out 5.14 g of a mixture containing unknown amounts of BaO(s) and CaO(s) and placed the sample in a 1.50-L flask containing CO₂(g) at 30.0^oC and 750. torr. After the reaction to form BaCO₃(s) and CaCO₃(s) was completed, the pressure of CO₂(g) remaining was 230. torr. Calculate the mass percents of CaO(s) and BaO(s) in the mixture.
