msolute en g; nsolute en mol; Vsolution en L; M masse molaire du solute en g.mol-1
n=m/M (liquide solide gaz)
m=n*M
M=m/n
n=p*v/M  (liquide)
 m/M
 
p=m/V (liquide)
n=V/Vm (gaz)
 
n= cxvsolution (soluté)

concentration en masse: Y= msoluté/vsolution en g.l-1
concentration molaire: C=nsoluté/vsolution mol.L-1

nmere=nfille donc Cmere x Vmere= Cfille x Vfille

-calcul de la masse molaire (donnes)
-quantite de matiere n=m/M mol
-concentrations C=n/V

=C=m/M*V
La dissolution modelisee par 3 etapes:
  -la dissociation des ions du solide
  -la solvatation (hydratation)
  -la dispertion
