Anouncements: We will be starting to take a variety of quizzes starting this Thursday on the Mole unit. This unit is crucial so if you do not understand go see Mr. Paek or the TLC!!
Homework: Finish the Pair, Dozen, Mole Lab!! (3 pages)
Today in class we started the new Mole unit and learned the concept of a mole in order to solve mole problems. We learned that 1 mole= 6.02 x 10E23 (10 to the 23rd power).
In order to fully understand the concept of a mole, we did a Mole Lab and started by reviewing the fact that a pair is always 2 and a dozen is always 12. Like those, a mole is always 6.02 x 10E23. 
During the lab, we practices converting problems involving the atoms mass in grams. Each elements atomic mass on the periodic table is the amount of mass measured in grams per mole. For example, Al has an atomic mass of 26.98.
26.98g of Al = 1 mole of Al
Another way of saying this is that for every 26.98g of Al, there is one mole of Al.
We also were able to add up the masses of two different atoms such as (H2O) two Hydrogen and one Oxygen so that we were able to figure out that there are 18.02g in a single H2O molecule. Like the concept Al's mass of 26.98g being a mole, 18.02g of H2O is equal to 1 mole as well.
