Gas Laws Calculations

A balloon of Argon gas has a volume of 150. mL when its pressure is 0.647 atm. What will the pressure of the gas be at a volume of 98.3 mL if the temperature remains constant?

• 0.987 atm
• 1.53 atm
• 2.36 atm
• 97.1 atm

A balloon of helium gas occupies a volume of 1 L at 32°C. What volume will the gas occupy if we put it in a ice bath at a temperature of 0°C, assuming pressure remains constant? HINT: Temperature units MUST be in Kelvin!

• 0 L
• 1.11 L
• 895 mL
• 632 mL

At STP, 1 mole of hydrogen gas (or ANY other gas for that matter) has a volume of 22.4 L. What would be the volume of a balloon if we used 0.15 moles hydrogen gas to fill it up?

• 0.0067 L
• 149 L
• 0.0067 mL
• 3.36 L

The gas in an aerosol can exerts a pressure of 3.00 atm at 25°C. Directions on the can warn the user not to keep the can in a place where the temperature exceeds 100°C. What would the gas pressure in the can be at 100°C?

• 3.76 atm
• 2.40 atm
• 12 atm
• 0.75 atm

For his chemistry demonstration, Davy filled up a 5 L balloon with nitrous oxide gas at 25°C and an atmospheric pressure of 1.08 atm. For easier transportation he stored it in a pressurized container at 1.5 atm and temperature of 5°C. What volume will the balloon have?

• 9.77 L
• 3.36 L
• 7.56 L
• 4.35 L

What is the temperature of natural gas in an oil pipeline if we know there are 0.91 moles of the gas in the pipeline and the volume of the pipeline is 5.43 L and the gas is exerting a pressure of 4.21 atm?
