hey guys, im finding this question really difficult and apart from getting the equations, i really don't know where to start. can any1 guide me in the right direction?
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 1.5L flask containing CO2(g) at 30 degrees C 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 of BaO(s) and CaO(s) in the mixture.
ok, well i wrote 2 equations: CaO + CO2 --> CaCO3 and BaO + CO2 --> BaCO3
i'm not sure what i should be aiming to do to get the mass of those 2 compounds...
thanx
