1. How many moles of a gas will fit into a 3.98 l container at 783 mm Hg and 56 degrees Celsius?

 

2. What is the temperature of a container if it has a volume of 4.57 liters, a pressure of 0.872 atm and contains 0.494 moles of carbon dioxide?

 

3. What will the pressure be in a container if it starts at 300 mm Hg and the temperature rises form 137 K to 137oC?

 

4. A balloon contains 4 moles of gas and has a volume of 6.91 liters.  What will the new volume be if 5.1 more moles of gas are added?

 

5. If the valve in the diagram below is opened, what will the final pressure be in the apparatus? (Hint: each gas expands as if the other were not there.)

 

 

 

 

 

 

6. You collect hydrogen over water (as you did in the lab).  If the vapor pressure of water is 23.71 mm Hg and the atmospheric pressure is 1.034 atm, what is the pressure of the hydrogen?

 

7. How many moles will fit into a balloon that has a volume of 4.50 L, at a pressure of 743 mm Hg, and a temperature of 200oC?

 

8. If a balloon that has a volume of 13.77 L is heated from 12 K to 12oC, what will the new volume be?

 

9. A container has a volume of 3.00 L.  If 2.00 moles of hydrogen are placed in the container at 12oC what will the pressure be?

 

If 1.00 moles of oxygen are added to the container at the same temperature, what will the pressure of the oxygen be?

 

What will the total pressure be?

 

If the two gases react and the final temperature of the gas afterwards is 348oC, what will the final total pressure be? (assume the V doesn't change)

HINT: Do the stoich problem to find the pressure of the product. Then find the amount of xs and calculate that pressure.

 

10. Carbon dioxide leaks out a container in 34 minutes and 28 seconds.  How long would it take nitrogen to leak from the same container (assuming that it started at the same temperature and pressure?
