6.02 x 1023 is
also known as
Avogadro’s
number.
(get it?)

In other words…
The Mole is a BIG number used to
describe things that are really small
...like atoms and molecules.
...so how big are we talking about???

Multiple Choice
6.02 x 1023 is also called __________ number
Avogadro's
Simpson's
Einstein's
Newton's

USE YOUR CONVERSION FACTOR…
GET RID OF “moles” USING SOMETHING IT IS EQUAL TO (atoms).
THEN CANCEL OUT AND SIMPLIFY
3.5 moles
1 mole
6.02 x 1023 atoms
3.5 x 6.02 x 1023 = 2.11 x 1024 atoms
