__Gas Law Problems __

1.) The gas pressure in an aerosol can is 1.5 atm at 25 ^{o}C. Assuming that the gas inside obeys the

ideal gas equation, what would the
pressure be if the can were heated to 450 ^{o}C?

2.) A pocket of gas is discovered in a
deep drilling operation. The gas has a
temperature of 480 ^{o}C

and is at a pressure of 12.8 atm. Assume ideal
behavior. What volume of the gas is
required to

provide 18.0 L at the surface at
1.00 atm and 22 ^{o}C?

3.) A fixed quantity of gas is compressed at constant temperature
from a volume of 368 mL to 108

mL. If the initial pressure was 5.22 atm, what is the final pressure?

4.) A gas originally at 15 ^{o}C
and having a volume of 182 mL is reduced in volume to
82.0 mL while its

pressure is held constant. What is its final temperature?

5.) At 36 ^{o}C and 1.00 atm pressure, a gas occupies a volume of 0.600 L. How many liters will it

occupy at 0.0 ^{o}C
and 0.205 atm?

6.) What is the temperature at which 9.87 x 10^{-2} moles
occupies 164 mL at 0.645 atm?

7.) Chlorine is widely used to purify municipal water supplies and
to treat swimming pool waters.

Suppose that the volume of a
particular sample of Cl_{2} is 6.18 L at 0.90 atm
and 33 ^{o}C.
What

volume will the Cl_{2 }occupy
at 107 ^{o}C and 0.75 atm?

8.) A gas exerts a pressure of 1.5 atm at 27 ^{o}C. The
temperature is increased to 108 ^{o}C with no

volume change. What is the gas pressure at the higher
temperature?

Answers:
1.) 3.6 atm
2.) 3.59 L or 3.6
L 3.) 17.8 atm
4.) 130 K or 130. K

5.) 2.59 L or 2.6
L
6.) 13.1
K
7.) 9.2
L
8.) 1.9 atm
