Moles Test #2 next class on section V.4-V.6.  Bring a scientific calculator.

Test outline:  Percent composition and Empirical and Molecular Formulas will comprise 50% of the test score.  Molarity and dilutions will comprise the other 50% of the test score.  The test will be all written.  Show your work!  Draw mole wheels!

Molarity and Dilutions Day 2

1.  I will be able to calculate the new molarity when a solution is diluted.

2.  Finish reading section V.6

3.  Do:  Review Questions #95-102 (odd #s)

Moles Test #2 on sections V.4-V.6 on Friday Jan 23 and Mon Jan 26.
