Try 3 free problems on moles, molar mass, percent composition, and formulas. Want more reps? Premium opens the full 174-problem bank in sets of 3, 9, or 18.
Work these 3 to find out whether the mole conversion path is clear enough to follow on your own — before the setup isn't right in front of you anymore.
#4Mole Conversion
How many grams are in 3.50 mol of calcium carbonate (CaCO3)? (Molar mass = 100.09 g/mol)
#5Avogadro's Number
What does Avogadro's number (6.022 × 1023) represent?
#6Empirical Formula
A compound contains 40.0% C, 6.7% H, and 53.3% O by mass. What is its empirical formula? (Atomic masses: C = 12.01, H = 1.008, O = 16.00)
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 grams-to-moles conversions, molar mass, particles, and empirical formulas
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
