Kinetic Theory and a Model for Gases Particles of gases are small and have insignificant volume. Particles move rapidly and randomly. All collisions are perfectly elastic.

What is the pressure (in mmHg) if a 3.0 L sample at 860 mmHg is reduced to a volume of 0.50 L?

A 2.0 L balloon at 21.0 o C is taken outside on a cold o C day. What would be the volume of the balloon?

What is the pressure (in kpa) in an aerosol can at 70.0 o C if its initial pressure and temperature was 206 kpa and 30.0 o C respectively?

A gas occupies ml at a pressure of kPa and a temp. of 19.0 degrees Celsius. The next day, it was measured at a pressure of kPa and a temp. of 11.0 degrees Celsius. What is the new volume?

How many moles of Argon gas are in a 34.0 liter sample at 1.4 atm and o C? (R = L x atm/mol x K)

At what temperature (in K) will 356 grams of sulfur dioxide occupy L at 895 torr?

3.876 grams of potassium sulfate is decomposed. What is the volume of the gas phase product if the temperature is 298 K and the pressure is 2.96 atm?

Calculate the volume of gas that would be generated by reacting grams of aluminum carbonate with excess HCl under lab conditions of 22.0 o C and 790mmHg.

“ Pig Dirt ” What is the GFM of a gas at 0.90 atm and 299 K if its density is 9.5 x g/L

A gas has a volume of 28.2 dm 3 at a temp. of 38.0 o C and a pressure of 72.6 kPa. Given that the mass of this sample is grams, what is the GFM?

. The decomposition of a sample of potassium chlorate generates 3.1 liters of oxygen gas at a pressure of 2.9 atm and a temperature of 309 K. How many grams of oxygen was produced?

A mixture of helium, oxygen and nitrogen gases have a pressure of 760 mmHg. If the partial pressure of helium is 31 mmHg and the partial pressure of oxygen is 467 mmHg, what is the partial pressure of nitrogen?

A sealed 5.00 L container with helium gas in it exerts a pressure of 1.23 atm. What will this pressure be if 0.35 moles of oxygen is added to this container (The temperature is 285 K.)?

A 2.00 L volume of chlorine gas, at a pressure of 45 kPa is mixed together with a sample of CO 2 gas with a volume of 1.20 L and a pressure of kPa. The new container has a volume of 7.00 L. Find the partial pressure of each gas in the new container, and find the total pressure.

Compare the rates of effusion of chlorine and Helium gases.

Compare the rates of effusion of hydrogen gas and radon gas
