Ideal Gas Law PV=nRT

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
• 8 L

Determine the temperature required for 0.0470 mol of gas to fill a balloon to 1.20 L under 0.998 atm pressure. 

• 200 K 

• 107 K 
• 207 K 
• 310 K 

• 300K

What does R stand for

• Ideal gas constant

• Real gas constant

• Temperature constant

• Ideal gas law

• Pressure constant

Determine the Celsius temperature of 2.49 moles of gas contained in a 1.00-L vessel at a pressure of 143 kPa. Solve for T and then change you answer to Celcius

• -266 degrees C
• -622 degrees C
• 622 degrees C 
• 266 degrees C

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

Please use kilopascals for pressure.

• 2222.08 moles
• 4.43 moles
• 22.4 moles 
• 76.8 moles

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 
• Kilojoules
