Exam 2: The Behaviour of Gases

Vinyl chloride is a important industrial chemical used in many different applications. However, it has health impacts even at the PPB level. If an average breath is about 1.5 L, how many vinyl chloride molecules would be contained in one breath, assuming 1 atm pressure and 26°C if the vinyl chloride concentration is 10 PPB?

Which of the following molecules/atoms will exert a greater force when it strikes the wall of the container under ideal conditions?

Data for a pulsed molecular beam experiment at a temperature of 297 K is shown below: Which are the following are probably true about the sample?1. The sample consists of two different molar mass molecules.2. The sample has a lower molar mass than ammonia (avg is 490 m/s).3. The sample has a higher molar mass than ammonia (avg is 490 m/s).4. The sample consists of molecules with the same molar mass.5. The average velocity is near 200 m/s.

Calculate the pressure of a gas under non-ideal conditions, and explain the deviations from ideality.
