introduction
Chemists deal with atoms and molecules all the time, and they need to measure quantities of matter precisely.
Since atoms and molecules are very small, the quantity used to measure them needs to be a very large number.
Proceeding clockwise from the top, samples containing one mole each of copper, aluminum, iron, sulfur, iodine, and (in the center) mercury.

The quantity that chemists use to measure elements and compounds.
Like a dozen, the mole represents a number. The number of particles in 1 mol is called Avogadro's number

Read page 107 to the top of 108. Be sure to look over Figures A3.23 and A3.24. These figures will help you visualize the mole concept.
Define the mole and Avogadro’s number, in your notes.
Read over page 111 and answer how the mole is related to chemical reactions in your notes.

As a review of this section, do questions #1-13 in the Check & Reflect on page 112.
Next: Once you have completed the required readings and learning activities for sections A3.1-3.4, you are now ready to complete the following lab:
Lab: "A3- Chemical Change Lab and Investigation- Investigating Evidence of Chemical Change "
Upon completion of the above lab you will be ready to complete the Unit Review- Self-Test.
Once you feel prepared after reviewing the course material for sections A3.1-3.4, you are ready for test permission for A3 Unit Test
For Test permission- you must bring the following to a Science teacher:
