Mole vs Molecule | Difference between mole and molecule

Q. What is the difference between a mole and a molecule?

Ans:

MOLE: A mole is a fixed number, that is 6.02x1023 it is also known as Avogadro's Number because Sir Avogadro was the person who calculated about 6.02x10 molecules and gave it the name "Mole". So mole is also used as unit for molecules. For example if we say one mole of hydrogen that means 6.02x10 molecules of hydrogen.

So.. The definition of atom is:

A group of atoms of same element bonded together.
