Concept of the Mole

The concept of the mole can be confusing to many as the mole is such an abstract terminology used in chemistry.

 

To break it down into simpler terms, a mole can be defined as a measuring unit such as a dozen, but instead of having 12 items in 1 dozen, a mole has 6.022 x 1023 things. The mole is indeed a gigantic number! The mole is a SI base unit and formally it is defined as the number of atoms found in exactly 12 g of pure carbon-12.

 

If you write out the amount found in 1 mole, you will get

 

1 mole = 602 213 670 000 000 000 000 000 of particles

 

This enormous number 6.022 x 1023 is called Avogadro’s number.
