  1. What is the Ideal Gas Law Equation?

    2.  

     

  2. From what laws is this equation derived?



     

  3. A sample of hydrogen gas has a volume of 8.56 L at a temperature of 0oC and a pressure of 1.5 atm. 
    • Calculate the moles of hydrogen present in the sample.
    • How would this answer change if the gas had been helium?

     

     

  4. What equation can you use if you are given a question in which there a change in state?

    5.  

     

  5. A sealed balloon is filled with 1.00 L of helium at 23oC and 1.00 atm.  The balloon rises to a point in the atmosphere where the pressure is 220. torr and the temperature is -31oC.  What is the change in the volume of the balloon as it ascends from 1.00 atm à 220. torr?

    6.  

     

  6. A bicycle tire is filled with air to a pressure of 75 psi at a temperature of 19oC.  Riding the bike on asphalt on a hot day increases the temperature of the tire to 58oC.  The volume of the tire increases by 4.0%.  What is the new pressure in the bicycle tire?


  7. Assuming constant temperature and pressure what would the final volume be for the following reaction after it has run to completion?

    8.  

     

  8. What is STP?

    9.  

     

  9. Consider


    What mass of NaN3 must be reacted in order to inflate an airbag to 71.4 L at STP?

    10.  

     

  10. A compound has the empirical formula CHCl.  A 256 mL flask, at 373K and 750 torr contains 0.800g of the gaseous compound.  Give the molecular formula.
                     

    11.  

  11. Consider:



    If this reaction is run at STP, what would the total volume be after this reaction has run to completion.
