Avogadro’s Law
According to Avogadro’s Law, an ‘equal volume of all gases contains the equal number of molecules under the same conditions of temperature and pressure.’
This law was proposed In 1811 by none other than Avogadro himself. In other words, this law states that the volume and number of moles of any gas are always directly proportional to each other. This means that two liters of hydrogen have the same number of molecules as two liters of oxygen at the same temperature and pressure.
Example of Avogadro’s Law
Equivalent volumes of different gases contain the same number of molecules at the same temperature and pressure. In the above example CL2 and H₂ has 1 volume each combines to form 2 volume of HCL.

Mole is a unit of measurement for substance. 1 mole substance contains 6.02214076×10²³ particles.

Laws of Chemical Combination
Laws of Chemical Combination are one of the most fundamental building blocks of the subject of chemistry. As in our surrounding different matter reacts with each other and form various kind of different substances. Laws of Chemical Combination are the collection of laws that explains how these substances combine together to form anything at all. When matter reacts with another matter, a chemical reaction happens which changes the form, properties, or characteristics of the matter drastically. This interaction of matter with each other is governed by the Laws of Chemical Combination.
