Answer :

Final answer:

Avogadro's law explains the direct relationship between gas volume and the number of moles in a sample at constant temperature and pressure.


Explanation:

Avogadro's law states that at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas in the sample. This means that as the amount of gas increases, the volume it occupies also increases in a predictable manner. Avogadro made this discovery by observing the relationship between gas volume and the number of particles (moles), laying the foundation for the concept of Avogadro's number.
