A 9m^3 room contains a canister of CO2 with a faulty valve. At a level of 75 mole % CO2, breathing the air becomes lethal. The room temperature is 25 degrees Celcius.
A) If the concentration of CO@ reaches the lethal 75 mole % level, what would be the mole % of O2?
B) How much CO2 (kg) is present in the room when the lethalconcentration is reached
