Resources for Empirical and Molecular Formulas
Students, I've found some locations to help you. Take a peek at http://www.chem.lsu.edu/lucid/tutorials/empiricalform.html
and http://chemed.chem.purdue.edu/genchem/probsolv/stoichiometry/index.html. Also, you might try http://dbhs.wvusd.k12.ca.us/webdocs/Mole/Empirical-MolecFormulas.html.
One more location is http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson59.htm.

A site with quizzes you can try is http://lrc-srvr.mps.ohio-state.edu/under/chemed/qbank/quiz/bank2.htm
Your test on chapter 6, the mole, will be on Friday, October 17. Be sure that you are working practice problems to ensure success.
