Choose the correct alternative:
The gas law which relates the volume of a gas to the number of molecules of the gas is:
(a) Avogadro's Law
(b) Gay-Lussac's Law
(c) Boyle's Law
(d) Charles' Law
Avogadro's law relates the volume of a gas to the number of molecules of the gas. It states that under same temperature and pressure conditions, the same number of molecules of different gases occupy equal volume.
Hence, the correct answer is option (a).
