How to understand avogadro's gas law?

Avon Gadereau's law and its inference are as follows:

Evan Gardlow's Law:

(1) at the same temperature and pressure, V 1/V2? =? n 1/n2

(2) At the same temperature and volume, p 1/p2? =? n 1/n2？ =? N 1/N2

(3) Equal mass at the same temperature and pressure, V 1/V2? =? M2/M 1

(4) At the same temperature, pressure and volume, M 1/M2? =? ρ 1/ρ2

Avon Gadereau's law holds that at the same temperature and pressure, the same volume of gas contains the same number of molecules. 18 1 1 year. This hypothesis was put forward by Italian chemist Avo Gardero and later recognized by the scientific community. This law reveals the volume relationship of gas reaction, which is used to explain the composition of gas molecules and provides a basis for determining the molecular weight of gaseous substances by gas density method. It has also played a positive role in the establishment of atomic and molecular theories.

Definition:

At the same temperature and pressure, any gas with the same volume contains the same number of molecules.

Scope of application:

Ideal gas (that is, gas molecules have no volume and there is no force between molecules. Attachment: Many gases are close to ideal gases at high temperature and high pressure. They can be single gas or mixed gas. It can be an elemental gas or a compound gas.
