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.
#4
Ideal 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)
#5
Charles'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…
#6
Dalton'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?
Prep for the test — not just the homework
The 3 free problems show you where you stand. The full bank is how you close the gaps before the test.
- Randomized every time — fresh problems that force real understanding, not answer memorization
- Full worked solutions — see exactly where your setup went off track, not just whether you were right
- 174 problems across Boyle's Law, Charles's Law, the Ideal Gas Law, and partial pressures
- Quick (3), Standard (9), or Extended (18) — use whatever fits your schedule
- Filter by type — focus on calculation, concept, or multi-step problems first
- Filter by difficulty — dial in easy, medium, or hard problems as you build up
