Gas Laws

If the pressure exerted by a gas at 25 degrees C in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

• .002766 mole
• .0069 mol
• 2.766 mol
• 9.887 mol

Calculate the volume that a 0.323-mol sample of a gas will occupy at 265 K and a pressure of 0.900 atm.

• 7.18 L 
• 7.81 L
• 4.63 L
• 4.36 L

What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase
• Decrease
• Nothing
• Explosion!

If you increase the pressure of a constant volume of gas, what will happen to the temperature?

• Increase
• Decrease
• Stay the same
• It will Blow Up

How are pressure and volume related?

• Directly
• Indirectly
• They aren't related

If a nitrogen gas occupies a volume of 500ml at a pressure of 0.971atm. What volume will the gas occupy at a pressure of 1.50 atm, assuming the temperature remains constant?  

• 323.6 ml
• 728.25 ml
• 772.39 ml
• None of the above

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL?

• 57.5⁰C
• 57.5 K
• 330.5 K
• 330.5⁰C

Gases have...
