You have a 550.-mL tank of gas with a pressure of 1.56 atm at 24°C. You thought the gas was pure carbon monoxide gas, CO, but you 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°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, and what is the partial pressure of each of the three gases at 25°C?
