Cornell Notes
Topic: The Mole and Molar Mass Date: 3/4/2014 Essential Questions:
What is a mole? Why do scientists use moles?
Cornell Notes
Topic: The Mole and Molar Mass
Date: 3/4/2014 A mole is a quantity used to
measure the amount of matter present.
Like a dozen = 12 A mole = 6.02 x 1023
A dozen doughnuts = 12 doughnuts
A mole of carbon = 6.02 x 1023 atoms (particles) of C
What is the
mole and
how is it
defined?
Brain Pop
While watching this video: Take notes on WHY we use the mole and
the importance of it. Think about how difficult it would be to
conduct experiments without the mole.
Brain Pop: Moles
Cornell Notes (continued)
Since the mole is always the same number, a mole of different elements or compounds will have different masses.
The mass of 1 mole was defined by Carbon-12. 1 mole of carbon = 12 g _
1 mol 6.02 x 1023 atoms carbon = 12 g
What is molar mass?
Cornell Notes (continued)
1. Determine types of atoms in a compound.
2. Find their atomic masses.3. Sum all masses! Units = g /
mol
How do you
calculate molar mass?
