Avogadro's Law was stated in 1811 by the Italian chemist himself Amedeo Avogadro(1776-1856) Avogadro work does relate to Gay-Lussac and Dalton's work and theories, how when two gases or reactants make a product of whole number ratios, but Dalton rejected this idea where Avogadro saw it as a key to understanding molecular constituency. In the year 1811, Avogadro made a distinction between atoms and molecules and thereby proposed Avogadro’s law. Avogadro proposed that, “Equal volumes of all gases at the same temperature and pressure contain an equal number of molecules”. Hydrogen gas combines with oxygen gas to produce water vapour as follows.

• Avogadro work does relate to Gay-Lussac and Dalton's work and theories, how when two gases or reactants make a product of whole number ratios, but Dalton rejected this idea where Avogadro saw it as a key to understanding molecular constituency.

• So Avogadro took two gases and put them under the same conditions and studied the molecular change in the gas(water vapor) and oxygen and noticed that the water vapor oxygen molecules had split.

• The law states, 'Equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical.'

• The next equation takes the pressure and temperature change into account and is said to be the more important equation from Avogadro's law:

Which Statement Best Describes Avogadro's Law

1. In the year 1811, Avogadro made a distinction between atoms and molecules and thereby proposed Avogadro’s law.
2. Avogadro proposed that, “Equal volumes of all gases at the same temperature and pressure contain an equal number of molecules”.
   e.g. Hydrogen gas combines with oxygen gas to produce water vapour as follows:
   [ce{underset{text{[2 vol]}}{underset{text{[100 mL]}}{Hydrogen}_{(g)}} + underset{text{[1 vol]}}{underset{text{[50 mL]}}{Oxygen}_{(g)}}->underset{text{[2 vol]}}{underset{text{[100 mL]}}{Water}_{(g)}}}]
   cording to Avogadro’s law, if 1 volume contains n molecules, then 2n molecules of hydrogen combine with n molecules of oxygen to give 2n molecules of water, i.e., 2 molecules of hydrogen gas combine with 1 molecule of oxygen to give 2 molecules of water vapour as represented below:
   [ce{underset{text{[2 molecules]}}{underset{text{[2n molecules]}}{Hydrogen}_{(g)}} + underset{text{[1 molecule]}}{underset{text{[n molecules]}}{Oxygen}_{(g)}}->underset{text{[2 molecules]}}{underset{text{[2n molecules]}}{Water}_{(g)}}}]
