1.) A mass of air
occupies a volume of 5.7 L at a pressure of 52.7 kPa.
What is the new pressure if

the same mass of air at the same temperature is
transferred to a 2.0 L container?

(Answer = 150 kPa)

2.) A volume of 20.0
L of O_{2} is warmed from -30.0 ^{o}C
to 85.0 ^{o}C. What is the new volume
if the

pressure is kept constant?

(Answer = 29.5 L)

3.) A rigid
container holds a gas at a pressure of 55 kPa at a
temperature of -100 ^{o}C. What will

the pressure be when the temperature is
increased to 200 ^{o}C?

(Answer = 150 kPa)

4.) What is the mass
of a sample of CO_{2} that has a volume of 75.0 mL
at 30.0 ^{o}C and 91.0 kPa?

(Answer = 0.119 g)

5.) What is the volume
of a sample of N_{2} that has a mass of 50.0 grams and is under a
pressure of

125 kPa at 27.0 ^{o}C?

(Answer = 35.6 L)

6.) Determine the
total pressure of a gas mixture that contains CO, Ne,
and He if the partial

pressures of the gases are P_{CO} = 155 kPa, P_{Ne} = 83 kPa, and P_{He} = 34 kPa.

(Answer = 272 kPa)
