2/28 HW – Gas Laws Review

 

1.    List the four variables that describe a gas and corresponding units for the variable.

 

2.    The gas in 14.0 L container exerts a pressure of 115 kPa.  What pressure is needed to compress the gas to 2.0 L while keeping the temperature constant?

 

3.    The gas left in a used aerosol can is at a pressure of 100 kPa at 27˚ C.  If the can is thrown into a fire, what will the internal pressure of the gas be when its temperature reaches 1000˚ C?

 

4.    A helium balloon has a volume of 450 mL at a temperature of 45˚ C.  What will be the volume of the balloon if you take the balloon to Orlando on a day that is 301 K?

 

5.    A pressurized gas container has a volume of 3.5 L at a temperature of 22˚ C.  If the container contains 4.56 kg of oxygen, what is the pressure inside the container?

 

6.    How many grams are contained in each of the following at STP?

       a.    22.4 L sulfur dioxide

 

       b.    5.60 L Cl2

 

       c.    0.125 L Ne

 

       d.    70.0 mL Ammonium chloride
