Gas Laws Practice Problems  1. A sample of nitrogen gas, N 2 , occupies 3.0L at a pressure of 3.0 atm. What volume will it occupy when the  pressure is changed to 0.50 atm and the temperature remains constant? (Boyle’s Law) 2. A sample of oxygen gas, O 2 , occupies 5.0 L at a pressure of 1.00 atm. What pressure is required to reduce the  volume of this gas sample to 50.0mL? (Boyle’s Law) 3. A sample of methane gas, CH 4 , occupies 4.50 L at a temperature of 20.0 o C. If the pressure is held constant, what  volume will the gas occupy if the temperature is increased to 200.0 o C? (Charles’ Law) 4. A sample of carbon monoxide gas occupies 10.00 L at an unknown temperature. When the gas sample is cooled  to a temperature of 22 o C it is found to occupy 75.0 mL. What was the original temperature of the gas sample?  (Charles’ Law) 5. The pressure of hydrogen gas in a constant-volume cylinder is 4.25 atm at 0

What pressure would this same tank have if the temperature rose to 1110 o C? (Gay-Lussacs Law) 7. A 325 mL sample of air is at 720.0 torr and 30.0 o C. What volume will this gas occupy at 800.0 torr and 75.0 o C? (Combined Gas Law) 8. A balloon is filled with helium to a volume of 4.0L at ground level (1.00 atm) on a warm day (34.0 o C). It is released and climbs to an altitude of 1500.0 meters * where the temperature is 25.0 o C and the pressure is 0.86 atm. What is the volume of the balloon under these conditions? *Mount Everest is 8,848 meters. The sears tower is 518 meters. (Combined Gas Law) 9. 10....
