Combined and Ideal Gas Law Practice Problems

There are _____ moles of gas that occupy 120 liters at a pressure of 2.3 atmospheres and a temperature of 340 K?

It is not safe to put aerosol canisters in a campfire, because the pressure inside the canisters gets very high and they can explode.  If I have a 1.0-liter canister that holds 2 moles of gas, and the campfire temperature is 1400 °C, the pressure inside the canister will be _____atm.

There is a type of balloon that can hold 100. liters of air.  If I blow up this balloon with 3.00 moles of air at a pressure of 1.0-atmosphere, the temperature of the balloon will be _____ °C.

If I have a 50-liter container that holds 45 moles of gas at a temperature of 200 °C, the pressure inside the container is _____ atm.

A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L.  If the temperature where the balloon is released is 20 °C, the volume of the balloon will be _____ L once it rises to an altitude where the pressure is 0.65 atm and the temperature is –15 °C?

Answer explanation

A gas balloon has a volume of 106.0 liters when the temperature is 45.0 °C and the pressure is 740.0 mm Hg. Its volume will be _____ L at 20.0 °C and 780.0 mm Hg pressure?

Answer explanation

The pressure of a gas is reduced from 1200.0 mm Hg to 850.0 mm Hg as the volume of its container is increased by moving a piston from 85.00 mL to 350.0 mL. The final temperature will be ____ °C if the original temperature was 90.0 °C?

Answer explanation

A gas is heated from 263.0 K to 298.0 K and the volume is increased from 24.0 liters to 35.0 liters by moving a large piston within a cylinder. If the original pressure was 1.00 atm, the final pressure will be ____ atm.
