 "THE CHEMIST'S DOZEN" AKA THE MOLE 

The mole is a unit that chemists use to count a huge number of atoms.  It has been called the chemist's dozen.  The mole is a unit that means a heap or pile of atoms, molecules, or particles.  

What I've done on this page is linked the topics to the actual PowerPoint Presentation that I used in class.  To access them just click on the link to the topic and follow the directions to access the presentations.  If you don't have PowerPoint on your computer you need to download the PowerPoint Viewer that is available for free through Microsoft Office.

Teachers:  If you would like to save the files themselves so you can edit them and use them in your classrooms you will need to right click on the link and choose the "save target" option.

Modern Chemistry Chap 3 Sec 3 .ppt Atomic Masses and the Mole
THE MOLE ADV .ppt This PowerPoint goes into an explanation of the unit that chemist's use to make the mass of an atom something realistic to work with.  The mole is a unit of amount used to count a specific number of particles of a compound.  It is such a large number of particles that it can be useful in a laboratory setting.  
THE MOLE GEN
THE EMPIRICAL & MOLECULAR FORMULA .ppt This PowerPoint goes into calculations of empirical and molecular formulas using mole math.
