Molecular Mass calculations

Today in class we went over worksheet 3-16 from yesterday.  I introduced the concept of molecular mass and used worksheet 3-18 as a demonstration.  Students worked with their partners to complete pages 3-17 and 3-18.
Homework is news article #13 for Monday.  The chapter 3 test will be on Thursday, December 10th.
