  2. Final Jeopardy

  3. 100 Ideal Gas Law How many moles of nitrogen gas are contained in a sample vial having a volume of 1.78 L if the temperature of the gas is 27.0oC and the pressure is 750.0 mm Hg?

  4. 200 Ideal Gas Law What type of gases, under what conditions, are most likely to deviate from the ideal gas law?

  5. 300 Ideal Gas Law Find the density of ammonia gas at 735 mm Hg and 25oC.

  6. 400 Ideal Gas Law An unknown gas has a mass of 0.846g and fills a bulb with a volume of 345 mL. The pressure is 752 mm Hg at 100oC . Find the molar mass of the gas.

  7. 500 Ideal Gas Law The density of a gas at standard temperature and pressure is 1.96 g/L. What is the molar mass of the gas?

  8. 100 Gas Laws A certain mass of chlorine gas occupies a volume of 50.0 mL at a temperature of 232 C and a pressure of 700 mm Hg. What volume will this same mass of gas occupy at STP?

  9. 200 Gas Laws A mixture of gases consists of 2 mol of N2, 1 mol of CH4, and 1.5 mol of O2. If the total pressure of this mixture is 850 mm Hg, what is the mole fraction and partial pressure of each gas?

  10. 300 Gas Laws A mixture of 0.0625 mol of O2 and .0507 mol of SO2 exerts how many atmospheres of pressure inside a 2.00 L container at 300K?

  11. 400 Gas Laws A sample of oxygen gas having a volume of 56.0 mL is collected by water displacement at a temperature of 20oC and a pressure of 710.0 mm Hg. Determine the volume of this oxygen sample as a dry gas at STP. (The vapor pressure of water is 17.5 mmHg at 20oC.)

  12. 500 Gas Laws Which laws, Boyles, Charles’, Gay-Lussac’s, and Avogadro’s are inverse, and which are direct, proportions? How do the graphs of each compare

  13. 100 Gas Movement Which effuses faster under the same conditions of temperature and pressure, O2 or SO2 gas?, Why?

  14. 200 Gas Movement Compare the velocity and kinetic energy of hydrogen and oxygen gas at the same temperature. Explain the relationship between their velocities mathematically.

  15. 300 Gas Movement Under the same conditions of temperature and pressure, methane effuses through a porous filter at a rate 2.3 times as fast as an unknown gas. What is the molar mass of the unknown gas?

  16. 400 Gas Movement Calculate the rms speed of helium gas at 20oC.

  17. 500 Gas Movement What units for rate can be used in Graham’s Law?

  18. 100 Potpourri What does STP mean? What are STP conditions?

  19. 200 Potpourri Why must Kelvin temperatures be used in gas law calculations? What is the meaning of 0K?

  20. 300 Potpourri When you collect a gas in a closed tube, how do you determine the pressure of that gas? Explain the calculation you might need to perform.

  21. 400 Potpourri A sample of nitrogen gas at 25oC and 765 mm Hg occupies a volume of 2.5 L. What volume will an equal number of moles of helium gas occupy at the same conditions?

  22. 500 Potpourri If 0.095 g of octane is completely combusted in excess oxygen, what will be the pressure of the water vapor formed in a 4.75 L flask at 30.0oC?
