Moles, moles, and more moles....

 My Co-op Chemistry class is in the trenches working on Moles.  All of this work is key to understanding the mole concept.  First, be sure your teen understands what a mole is.  Try Texas Gateway.  Here is a lecture, study guide, Molar Mass, and Mole Conversions.  Don’t forget to use Khan Academy for more help.  The more hands-on labs, conversions, and problem sets your teen tackles the better.  Take your time and work through Experiment 5.1, which is almost like a series of proofs.
