Question

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?

Part C

What is the volume fraction of chlorine in the storage room?
Express the volume fraction numerically

Explanation / Answer

At 101 atm, the cylinder contains (0.600 L) * (101) = 60.6 L of gas.

The volume of the room is (8.00 m) * (7.50 m) * (3.00 m) = 180 m3.

Since 1 m3 = 1000 L, the volume is 180000 L .

The volume fraction of chlorine is then (60.6 L) / (180000 L) = 3.36 * 10-4 .
