Question

What is the Avogadro's principle?

Answer 1

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....`Vpropn`...where `n="number of gaseous particles..."`

WE can use these ideas to formulate `"Avogadro's number"`, the number of particles in ONE mole of substance…`N_A=6.022xx10^23*mol^-1`.
