GenChem QUIZ - TOMORROW 10/12/2012

Our quiz tomorrow will cover the following topics...

Moles, Mole Conversion, Metric System

Here is a packet containing a metric ton of practice problems WITH ANSWERS - and some typos!.  I will be selecting from this packet EXACT questions that I will use for your quiz.  Note: this packet does not follow two of our rules.  Remember, when determining molar mass (molecular weight) round to two numbers past the decimal when using the average atomic masses on the periodic table.  Also, the answers on this sheet are not rounded to the correct number of significant figures.  Think about that as you compare your answers to the answer keys.

QUIZ REVIEW PACKET

AP CHEMISTRY - LAB TOMORROW

You will be designing and executing a lab tomorrow to determine the UNKNOWN concentration of a specific colored electrolyte solution.  I have provided you a few resources to get your mind going.  You will not know the electrolyte until tomorrow.  You will have a stock solution of KNOWN concentration already created.  Your goal will be to determine the unknown concentration that I give you.  The following links include a video, a student written lab report and a 'cook book' lab from another AP class.  The last link is a prezi used to describe Beer's Law.  Use them wisely to develop your method.
