Try 3 free Unit 12 practice problems to get your footing. When you want more reps on gas-law setups, pressure units, and PV = nRT, premium unlocks Quick Sets of 3, Standard Sets of 9, and Extended Sets of 18 from this 84-problem bank.
3 Free Sample Problems
Work these 3 to find out whether the gas law relationships are becoming automatic — or whether you need a few more deliberate passes before they are.
#4Ideal Gas Law
How many moles of gas are in a 5.00 L container at 2.00 atm and 300 K? (R = 0.08206 L·atm/mol·K)
#5Charles's Law
A gas occupies 2.00 L at 300 K. If the temperature rises to 600 K at constant pressure, the new volume is…
#6Dalton's Law
A gas mixture contains N2 at 0.60 atm, O2 at 0.25 atm, and CO2 at 0.10 atm. What is the total pressure and the mole fraction of N2?
