1) The volume of a gas at 21◦C and 0.27 atm
is 62 mL. What volume will the same gas
sample occupy at standard conditions?
Answer in units of mL.
2) A 739 mL gas sample at STP is compressed to
a volume of 244 mL, and the temperature is
increased to 24◦C. What is the new pressure
of the gas in Pa?
3) An aerosol can contain gases under a pressure
of 4.5 atm at 24 ◦C. If the can is left on a
hot sandy beach, the pressure of the gases
increases to 4.66 atm. What is the Celsius
temperature on the beach?
4) A sample of carbon dioxide gas occupies
564 mL at 0.868 atm and 6 ◦C. What will
the pressure be at a volume of 877 mL and a
temperature of 17 ◦C?
5) What pressure is required to reduce 62 mL of
a gas at standard conditions to 16 mL at a
temperature of 25◦C?
6) The volume of a gas is 26.1 mL at 22◦C and
0.926 atm. What will the volume be at 12◦C
and 0.993 atm?
7) A gas has a volume of 1.94 L at −17◦C and
190 kPa. At what temperature would the gas
occupy 1.03 L at 222 kPa?
