The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.
For example:
The balanced chemical equation for production of water from hydrogen and oxygen is:

That means 2 moles of
reacts with 1 mole of
to give 2 moles of
.
The given formula is
.
Hence, 4 represents the number of moles in
formula that is 4 moles of
.
