# Is the Avogadro constant used in the Avogadro's law formula?

##### 1 Answer

The mathematical expression for Avogadro's law is

So, what that above equation suggests is that there is a relationship between the volume a gas occupies and how much of that gas is present; this takes place for **constant temperature** and **constant pressure**, which, using the ideal gas law, implies that

To answer your question, Avogadro's number is not used in the formula for Avogadro's law; however, it could be, if you take into account the fact that

If you multiply the ideal gas equation by

where **Boltzmann's constant** =

So, in this form,
