Sample questions

  1. Five repeated measurements of the mass of the same sample (g) are: Trial 1 = 27.91; Trial 2 = 27.06; Trial 3 = 27.05; Trial 4 = 27.03; Trial 5 = 27.06. Which trial is most likely an outlier?
  2. A 32 mL aliquot at 0.6 mol/L is diluted to 96 mL total without reaction or loss. Find the final concentration. Round to 3 decimal places if needed. Answer in mol/L.
  3. Measured from the same origin, a spot travels 36 mm and the solvent front 56 mm. Find Rf. Round to 3 decimal places if needed.

Using the three versions

  • Start everyone with the same short explanation, then hand out Support, Core or Challenge.
  • Question numbers line up across the versions, so you can go through the answers with the whole class.
  • The PDF has a cover page and each version on its own pages; the answer keys PDF has all three keys.
