Questions 20 (20 challenge)
Grade range Grades 9 to 12
Topics Chemistry Sample questions An ideal gas occupies 16 L at 400 K. With pressure and amount fixed, find its volume at 1200 K in L. An ideal decay model starts with 192 mg. What expected mass remains after 3 half-lives, in mg? Dilute 230 mL of a 1.6 mol/L solution to 0.2 mol/L without losing solute. Find the final volume in mL. 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. See the original worksheet or browse more three-level worksheets .
