A 30.0-liter cylinder of gas containing 97.0 mole % CO and 3.0% CO2 is delivered to your plant. You sign the receipt for it, noting that the gauge on the tank reads 2000 psi. Several days later you notice that the gauge reads 1875 psi, indicating a leak. The storage room in which the cylinder is kept has a volume of 24.2 m3 and is very poorly ventilated. Calculate the maximum mole% of CO in the room at the time...
