1. Answers the questions below based on the graph to the right given the indicated title.
_____ (a) Title: Gas X at Three Different Temperatures
# of particles
Question: Which curve represents the highest temperature? _____ (b) Title: Gases X, Y, and Z at the Same Temperature Question: Which curve represents the gas with the highest molar mass?
B
C
Velocity
2. What is the root mean squared velocity of xenon gas at 21.1°C?
3. A sample of an unknown gas diffuses a certain distance in 11.10 min. A sample of H2 in the same apparatus under the same conditions diffuses the same distance in 2.42 min. What is the molar mass of the unknown gas?
CHEM 1A – Chapter 9 – Page 1 of 4
4. A compressed air tank carried by scuba divers has a volume of 8.0 L and a pressure of 140 atm at 20.0°C. If released from the tank, what would the volume of the gas be at 25.0°C and 1.00 atm?
5. Ammonium nitrate can decompose explosively when heated according to the equation 2 NH4NO3 (s) 2 N2 (g) + 4 H2O (g) + O2 (g) How many liters of gas would be formed at 450°C and 1.00 atm pressure by an explosion of 450 g of NH4NO3?
6. The drawing to the right represents a container holding a mixture of four gases, red, blue, green, and black. If the total pressure inside the container is 420 mm Hg, what is the partial pressure of the blue gas?

7. Consider two 1 L samples of gas: one is H2 and the other is O2. Both are at 1 atm and 25°C. Circle one answer per line to show how the two samples compare.
H2 (a) number of gas particles (b) mass (c) density (d) average kinetic energy (e) root mean squared velocity (f) rate of effusion
more heavier more dense higher higher faster
O2 same same same same same same
more heavier more dense higher higher faster
8. In a collision of sufficient force, automobile air bags respond by electrically triggering the explosive decomposition of sodium azide (NaN3) to its elements. A 50.0 g sample of sodium azide was decomposed, and the nitrogen gas generated was collected over water at 26.0°C. The total pressure was 745.5 mmHg. How many liters of dry N2 were generated? (PH2O = 25.2 torr at 26.0ºC)
9. What is the molar mass of a gas with a density of 1.342 g/L at STP?

10. A steel container with a volume of 500.00 mL is evacuated, and 25.0 g CaCO3 is added. The container is heated to 1500. K, causing the CaCO3 to decompose completely according to the following equation: CaCO3 (s) CaO (s) + CO2 (g) Accounting for the volume of solid remaining (dCaO = 3.34 g/mL), use van der Waal’s equation to calculate the final observed pressure in the container (for CO2: a = 3.59 atm·L2/mol2, b = 0.0427 L/mol)
