REVIEW

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?
