How do you convert Celsius to Kelvin?

• Divide by 273

• Multiply by 273

• Subtract 273

• Add 273

What is the volume of helium gas at 1.7 atm and 41 degrees Celsius?

• 34.87 L

• 36 L

• 35 L

• 33 L

If the pressure of a gas is measured in kPa instead of atm, what should you do?

• Use kPa directly without conversion

• Multiply kPa by 273

• Convert atm to kPa

• Convert kPa to atm

What is the final temperature in Celsius when 3.24 moles of CO2 gas are at a pressure of 2.15 atm and occupy a volume of 35.28 liters?

• 12 degrees Celsius

• 20 degrees Celsius

• 15 degrees Celsius

• 10 degrees Celsius

How many significant figures should the final answer have if the least precise measurement is 2.3 moles?

• Two

• Three

• One

• Four

What happens to the units when calculating with the ideal gas law?

• They cancel out leaving the desired unit

• They are all converted to atm

• They are all converted to Kelvin

• They remain unchanged

What is the correct way to rearrange the ideal gas law equation to solve for volume (V)?

• V = RT / nP

• V = nP / RT

• V = nRT / P

• V = Pn / RT

What should you do if R is on the bottom of the fraction when rearranging the ideal gas law equation?

• Flip R upside down

• Divide both sides by R

• Leave R as it is

• Multiply both sides by R

What unit is left after canceling out all other units when solving for temperature in the ideal gas law equation?

• Atmospheres

• Moles

• Liters

• Kelvin
