This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.

Under the same temperature and pressure conditions, equal volume of all gases contain the same number of molecules
Equal volumes of all gases, at the same temperature and pressure, have the same number of molecules
Avogadro's law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
Equal amounts of all gases have the same volume at the same conditions.
Blowing a balloon is an example of Avogadro's law because as you blow air into the balloon, the number of gas molecules increases. This results in an increase in volume within the balloon while keeping the pressure and temperature constant, illustrating the relationship between the volume and the number of gas molecules in the balloon.
1 mole has 6,022 140 857 (74).1023 molecules, atoms, ions.
Avogadro's Theory states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This theory led to Avogadro's Law, which states that the volume of a gas is directly proportional to the number of moles of gas present.
1 mole of any compound or element contains Avogadros Number (6.023 X 1023) molecules or atoms So 877 moles contains 877 X (6.023 X 1023) = 5.282 X 1026
