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
.
The number of atoms of sodium,
in
is:

The number of atoms of sulfur,
in
is:

The number of atoms of oxygen in,
in
is:

Alcohol consumption can damage the digestive system and can increase the risk of alcohol-caused cancer and liver disease.
If you draw or search for the molecular geometry of NOCl, you would know that it has a bent shape. This bent shape is a characteristic of a polar molecule. The dominant intermolecular forces for polar compounds is the <em>dipole-dipole force</em>.
