In one molecule of ${P}_{2} {O}_{3}$ there are 2 atoms of P and 3 atoms of O.

In two molecules of ${P}_{2} {O}_{3}$ there are 4 atoms of P and 6 atoms of O.

#### Explanation:

The ${P}_{2} {O}_{3}$ Molecule has
2 atoms of Phosphous
and
3 atoms of Oxygen

The coefficient 2 tells us we have
2 molecules of ${P}_{2} {O}_{3}$ which means we have a total of

4 atoms of Phosphorus
and
6 atoms of Oxygen
