The basic International System unit of amount of substance equal to the amount containing the same number of elementary units as the number of atoms in 12 grams of carbon-12.

SIMPLE WORDS
it is used to count the atom and like in mole there are 6.02*10^23 atoms.

A mole is an amount of molecules or atoms equal to the atomic weight of that substance in grams. For example, a mole of Oxygen (O2) is 32 grams, since the atomic weight of O2 is 32. It is also equal to 6.02 X 10^23 individual units. The mole is an important basic concept to understand since it has many uses in a number of chemical problems.

It is a word used to indicate a certain number of things. Just like a "dozen" is a word that means "12 things", a mole is a word that means 6.02 times 10 to the 23rd power things. That number, 6.02 * 10^23, is also called "avogadro's number". In chemistry the word mole is usually used to refer to a number of atoms or molecules.

So a mole of hydrogen atoms is 6.02 * 10^23 hydrogen atoms. A mole of carbon dioxide molecules is 6.02 * 10^23 CO2 molecules. 3 moles of gold atoms is 18.06 * 10^23 gold atoms.

Hope this helps, and Have Fun with It!

The mole is a unit that measures an amount of substance. One mole contains approximately 6.02×10^23 entities (usually atoms). One mole of a element is it's atomic weight.

Amount of substance of variable weight(depending upon type of element or compund) containing 6 X 10^23 particles.

Particles may be ions, atoms, molecules, radicals.....

I hope that helps!!
