# What is the Avogadro's principle?

May 27, 2018

This was proposed as one of the earliest gas laws...

#### Explanation:

Avogadro's hypothesis proposes that at the SAME TEMPERATURE and PRESSURE, EQUAL VOLUMES of gases contain the same number of particles....

And so....$V \propto n$...where $n = \text{number of gaseous particles...}$

WE can use these ideas to formulate $\text{Avogadro's number}$, the number of particles in ONE mole of substance…${N}_{A} = 6.022 \times {10}^{23} \cdot m o {l}^{-} 1$.
