Lethal concentrations of gases are often expressed in terms of volume fraction, that is, the fraction of available space occupied by the hazardous gas. A hazardous-materials worker wants to calculate the volume fraction of chlorine gas in a storage room after all of the contents of a 0.600-L cylinder of chlorine gas at 101 atm is accidentally released in the room. The environment in the storage room is kept at a constant pressure of 1.00 atm and a constant temperature of 20.0 °C. The room's dimensions are 8.00m×7.50m×3.00m. What is the volume fraction of chlorine gas present in the storage room?
