You have a 550 mL tank of gas with a pressure of 1.56 atm at 24.0°C. You thought the gas was pure carbon monoxide but later found it was contaminated by small quantities of gaseous CO2 and O2. Analysis shows that the tank pressure is 1.34 atm (at 24.0°C) if the CO2 is removed. Another experiment shows that 0.0870 g of O2 can be removed chemically. What are the masses of CO and CO2 in the tank?
