Basic Gas Laws / Combined Gas Law

A gas that has a pressure of 2 atm and a volume of 10 L.  What would be the new volume if the pressure was changed to 1 atm?

• P1/T1 = P2/T2
• P1V1 = P2V2
• V1/n1 = V2/n2
• PV = nRT

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?

• Pt = P1 + P2 + P3 + ...
• P1V1 = P2V2
• V1/T1 = V2/T2
• P1V1/T1 = P2V2/T2

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

• P1V1 = P2V2
• PV = nRT
• P1/T1 = P2/T2
• V1/n1 = V2/n2

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

• P1V1 = P2V2
• PV = nRT
• P1/T1 = P2/T2
• V1/n1 = V2/n2

Determine the number of moles in a container of gas at STP with a volume of 99.2 L. 

• V1/n1 = V2/n2
• PV = nRT
• P1/T1 = P2/T2
• V1/T1 = V2/T2

A sample of gas with a volume of 30.0 mL at 25.0^oC is heated to 50.0^oC.  What is the new volume of the gas?

• P1V1 = P2V2
• P1/T1 + P2/T2
• PV = nRT
• V1/T1 = V2/T2

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?

• P1/T1 = P2/T2
• PV = nRT
• V1/n1 = V2/n2
• P1V1 = P2V2

You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L
• 20 L
• It would stay at 10L
• 1 L
