Avogadro's law—Physical law stating that equal volumes of different ideal gases at the same temperature and pressure contain equal numbers of particles (molecules or atoms).
The interpretation of the law lies in the statistical–mechanical theory of equipartition of energy, and the ideal gas law is a consequence of this. The volume occupied by one mole of gas (see Avogadro's number) is the same for all gases (22.414 L)
Avogadro's number—The number of molecules (6.02214 × 1023) in one mole of gas.
That this number is a constant for permanent gases is Avogadro's law.
Loschmidt's number—Avogadro's number per unit liter, that is, 2.687 x 1022 per liter.
mole—A unit of mass numerically equal to the molecular weight of the substance.
The gram-mole or gram-molecule is the mass in grams numerically equal to the molecular weight; for example, a gram-mole of oxygen is 32 grams. (alikegram-molecular weight)

What happens on change in tempreture & pressure? What does it mean "equipartition of energy"?
I do not dispute on non presence of molecule
roughly above 12C or 24X as you should have considered simple logic of molecules per ml or per gram instead of per gaseous volume & if molecules can't come out from glass or eqipments used. Mole is not a form but just a number per unit. We can calculate, molecules per ml or per gram or per volume. But we should not calculate on the basis that same nos of molecules will be there as in given volume of gas. We should calculate on per ml or per gram basis taking total quantity of contents in quantity in whole solution. I don't think that there can be same numbers of molecules in one ml or one gram or per volume of every substance similarily. You can do that, I think by taking atomic weight of the constituents of molecules.
Molecular weight or gram molecular weight is different for different substances. While calculating molecular presence in homopathic remedies, numbers of molecules per gramme or per mililiter is to be taken. To calculate it we should know gram molecular weight of raw remedy substance & carriers. But we may not be knowing gram molecular weight of organic based remedies. Acordingly, it can be wrong to calculate by considering numbers per gaseous volome instead of per ml or per gram. Pressure & tempereture differences can be there in solid, liquid & gaseous forms of same substance. Eg; liquid gas.
