Moles!. Whatcha talkn’ about a mole? First…a dozen. 12 cookies = 12 bagels = 12 cans = 12 footballs = 12 dance moves = As scientist we need to determine.

CHEM 121 Chapter 5 1. The Mole 12 eggs = 12 bagels = 6.02 x 10 23 hydrogen atoms = 6.02 x 10 23 water molecules = 2 How many water molecules are in 3.5.
WHAT DO THE COEFFICIENTS IN A REACTION TELL US??!?! Consider the equation: – 2 H 2 (g) + O 2 (g) 2 H 2 O (l) The coefficients indicate: “Two molecules.
Moles!
