This the number of molecules that participate in the reaction as written..

#### Explanation:

Example: By considering the following reaction

$C {H}_{4} + 2 {O}_{2} \to C {O}_{2} + 2 {H}_{2} O$

The stoichiometric coefficient of $C {H}_{4}$ is 1

The stoichiometric coefficient of ${O}_{2}$ is 2

The stoichiometric coefficient of $C {O}_{2}$ is 1

The stoichiometric coefficient of ${H}_{2} O$ is 2
