CCU1 Mole conversion CoL

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???

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

SIMPLIFY AND CANCEL OUT THE 'ATOMS'

5.14 x 10²⁴ atoms

1 mole

​6.02 x 10²³ atoms

​6.02 x 10²³ atoms

​5.14 x 10²⁴ atoms

​= 8.54 moles
