SE UTILIZEAZA relatiile cu care se calculeaza numarul de moli
niu=V/Vm si niu=N/N,A----------> V/Vm=N/N,A-->V=NxVm/N,A
N,A= 6,023X10²³ molec/mol , numarul lui Avogadro
a) V=6,023X10²⁸x22,4/6,023X10²³ L=22,4X10⁵L
b) 12,046x10²⁵x22,4/ 6,023x10²³ l=200x22,4 l= 4480 l
a) 1molCl2............6.023×10^23moleculeCl2
X..........................6.023×10^28molec Cl2
X=6.023×10^28/6.023×10^23=1×10^5= 100000moli
1mol..............22.4l
100000........y
y=22.4×10^5 l
b) 1molNH3..........6.023×10^23molec NH3
X..............12.046×10^25molec NH3
x=12.046×10^25/6.023×10^23=2×10^2=200 moli
1moli...........22.4l
200moli.....y
y=22.4×200=4480l
