Question

A gas cylindar contains only the gases radon, nitrogen, and helium. The radon has a pressure of 222 torr while th nitrogen has a pressure of 446 torr, if the total pressure inside the cylindar is 771 torr what is the pressure that is due to the helium?

103 torr

771 torr

668 torr

549 torr

Part B

All of the following statements are constant with kinetic molecular theory EXCEPT

1. Strongactive forces hold the gas molecules together

2. The gas molecules colide with eachother and with the surfaces around them

3. The size of the gas molecules is neglectible compared to the volume of gas

4. The average kinetic energy of the molecules of a gas is proportional to the temperature of gas in the Kelvins

Explanation / Answer

pressure due to helium=771-446-222

=103 torr

2)1. Strongactive forces hold the gas molecules together
