What is a Mole?
A mole is a word which
represents a number.
Like the word "dozen" represents the number 12,
so "mole" represents the number 6 x 1023.
This number is also called Avogadro's Number -
It is a very very big number (6 followed by 23 zeros).
In the same way that you can
have a dozen atoms, or cars, or apples,
so you can also have a mole of atoms, or cars, or apples
(though it would take you a long time to eat them all!).
Needless to say,
chemists are concerned
with atoms, ions, molecules and compounds.
