Mol-modda miqdori(maruza)

Harorat va bosim n=PV/RT		MOL
Hajim n=V/Vm
	Molekular soni n=N(molekula) /NA		Atomlar soni n=N(Atom) /NA *K

Mol tushumchasi bilan bir qatorda gr-atom, gr-molekula tushumchalari ham ihlatiladi
1 gr-atom(1 mol atom) atomlar uchun qo’llaniladi , 1 gr-molekula (1 mol molekula) molekulalarni miqdorini anglatish uchun qo’llaniladi !!!
