Answer:

How else but by experiment....?

Explanation:

Avogadro's Law is one of the early gas laws, and proposed that the volume expressed by a gas was proportional to the number of gaseous molecules given equivalence with respect to temperature and pressure, #Vpropn#. And please note that the behaviour of gases in these scenarios allowed chemists and physicists to get a pretty shrewd idea of molecular behaviour simply by measurement of the macroscopic observables of mass, temperature, pressure, and volume.

Avogadro's original law proposed that #V_"volume of gas"propn_"number of gaseous particles"#...i.e. #V=kn#...with #k="some constant of proportionality"#
