How to find the number of molecules

A. Avogadro in 1811, at the very beginning of the development of atomic theory, made the assumption that an equal number of ideal gases at the same pressure and temperature contain the same number of molecules. Later this assumption was confirmed and became a necessary consequence for the kinetic theory. Now this theory is called Avogadro.

Avogadro's Law:

One mole of absolutely any gas, if the temperature and pressure are the same, will occupy the same volume of molecules. Under normal conditions, this volume is - 22.41383 liters. This value determines the molar volume of the gas.

The constant Avogadro shows the number of atoms or molecules that are contained in one mole of a substance.

The number of molecules, provided that the system is one-component, and the molecules or atoms of the same type contained in it, can be found by the special formula
