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 O2 is warmed from -30.0 oC
to 85.0 oC. 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 oC. What will
the pressure be when the temperature is
increased to 200 oC?
(Answer = 150 kPa)
4.) What is the mass
of a sample of CO2 that has a volume of 75.0 mL
at 30.0 oC and 91.0 kPa?
(Answer = 0.119 g)
5.) What is the volume
of a sample of N2 that has a mass of 50.0 grams and is under a
pressure of
125 kPa at 27.0 oC?
(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 PCO = 155 kPa, PNe = 83 kPa, and PHe = 34 kPa.
(Answer = 272 kPa)
