. Breathing air containing an asphyxiant (gas that is not toxic but excludes oxygen from the lungs when inhaled) is an extreme hazard and can lead to death. When the mole percent of the asphyxiant in the air reaches 50 mol%, symptoms of respiratory distress appear. At 75 mol%, unconsciousness and death occur in minutes. A small storage room, with dimensions 2m x 2 m x 3 m is used to storage liquid CO2 . A small leak in one of the CO2 cylinders allows some CO2 to escape. The room temperature is 25o C and atmospheric pressure.
2. Breathing air containing an asphyxiant (gas that is not toxic but excludes oxygen from the
lungs when inhaled) is an extreme hazard and can lead to death. When the mole percent of
the asphyxiant in the air reaches 50 mol%, symptoms of respiratory distress appear. At 75
mol%, unconsciousness and death occur in minutes. A small storage room, with dimensions 2m x 2 m x 3 m is used to storage liquid CO2 . A small leak in one of the CO2 cylinders allows some CO2 to escape. The room temperature is 25o C and atmospheric pressure.
a. Assuming air is 21.0 mol% O2 and 79.0 mol% N2, what is the mole percent of
O2 in the room when CO2 reaches the 50% hazard concentration?
b. How much CO2 in kg is present in the room when the lethal concentration is reached?Why would more than that amount have to escape from the cylinder for this
concentration to be reached?
