How does Avogadro’s law explain Gay-Lussac’s law of gaseous volu

1.	How does Avogadro’s law explain Gay-Lussac’s law of gaseous volumes ?
Answer» Avagadro’s law states that equal volumes of all gases contain equal number of molecules under similar conditions of temperature and presure. Since, when gases react chemically, they do so in volumes which bear a simple whole number ratio to each other and to the volume of products, provided the products are also in gasesous state under similar conditions of temperature and pressure. This is what Gay Lussac’s law states. For example, in the reaction of carbon monoxide with oxygen, two volumes of carbon monoxide react with one volume of oxygen to give two volumes of carbon dioxide under similar conditions of temperature and pressure. 2CO + O₂ —> 2 CO₂ 2 vol. 1 vol. 2 vol. The volume ratio of carbon monoxide, oxygen and carbon dioxide is 2 : 1 : 2.

2CO + O₂ —> 2 CO₂

2 vol. 1 vol. 2 vol.

The volume ratio of carbon monoxide, oxygen and carbon dioxide is 2 : 1 : 2.
