Question

A vessel contains a gaseous mixture of composition by volume 80% H2, and 20% CO. It is desired that the mixture should be made in the proportion 50% H2 and 50% CO by removing some of the mixture and adding some CO. Calculate, per kilomole of mixture, the mass of mixture to be removed and the mass of CO to be added. The pressure and temperature in the vessel remain constant during the process. Take the molar mass of H2 and CO as 2 kg/kmol and 28 kg/kmol, respectively. Hint: Since pressure, temperature, and volume did not change, the amount of substance (number of kilomoles) must remain the same throughout.
