Chemical Quantities


  • Do Mr Guch’s “Moles Worksheet” with answers (pdf).
  • Do Mr. Guch’s “Molar Mass Worksheet” (pdf) which has the answers.
  • Do Mr Guch’s “Moles Molecules, and Grams”(pdf and “Mole Calculation” (pdf) worksheets. Both have answers.
  • Have students do the “Chemical Quantities” (doc) crossword puzzle.
  • Try the “Chemical Quantities” (doc) wordsearch with answers (doc).
  • Try the online Stoichiometry “wordsearch” or “concentration” Java game.
  • And my favorite–have students use stoichiometry to solve a murder mystery in ChemCollective’s program, “Mixed Reception.” The program is free and can be run from a CD. With my class, it took 2 1/2 blocks in our computer lab. Since our lab doesn’t have speakers for every computer, I showed all the videos to the whole group using a projector like the Boxlight.  “Mixed Reception” can now be found in a Flash version and run directly from the website. However, the free CD’s are still available.
  • Have students do this “MOLEcular Mathematics” worksheet.
  • Show “The Mole Concept” slide presentation.
  • Show this YouTube video with “The Mole Is a Unit” song.
  • If you happen to be covering this topic during March Madness, you might want to try “Scooby-doo and the Case of Molarity Mayhem” (doc) with your class. It was contributed by Janine Towle of the NSTA Listserve.
  • Try Carole Henry’s “S’more Stoichiometry” (doc) worksheet with answers (pdf).
  • Or have student’s do Karen Belciglio’s “Fun with Moles” (doc) activity.


  • Do the “Percent Sugar in Bubble Gum” (doc) lab and have students calculate the molar mass of the sugar, convert the mass of the sugar to moles, and determine the number of molecules of sugar in the gum.
  • Do “The Volume of 1 Mole of Hydrogen Gas” (doc) lab.
  • Or try “The Determination of Relative Atomic Mass” (doc) lab.
  • Do the “Molar Volume of a Gas” lab.
  • Try the “Finding the Formula of an Oxide of Copper” (doc) lab.
  • Do the “The Stoichiometry of S’mores” (pdf) lab.
  • In “The Stoichiometry of Cooking” (pdf) by Lisa Morine, student’s in each group vary the amount of one ingredient for baking cupcakes to see how it affects the final product. Ms Morine includes a teacher’s guide (pdf).
  • In this “Periodic Table Hopscotch Laboratory” (pdf) students calculate the quantities of chalk used on a sidewalk. It includes a teacher’s guide (pdf).
  • Try the “Percentage of Water in Popcorn” (doc) lab.
  • Do this “What’s the Concentration of Kool-Aid?” (doc) lab. 
  • In the “Mole-to-Mole Relationships in a Chemical Reaction” lab, students carry out a reaction between metallic copper atoms and silver ions in solution to produce copper ions in solution and metallic silver atoms.
