Gas Laws Practice

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

• Increase
• Decrease
• Nothing
• Explosion!

How are pressure and volume related?

• Directly
• Indirectly
• They aren't related

Calculate the volume that a 0.323-mol sample of a gas will occupy at 265 K and a pressure of 0.900 atm (R = 0.0821).

• 7.18 L

• 7.81 L

• 4.63 L

• 4.36 L

If the pressure exerted by a gas at 298 K 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
