Nombre d'entité : 
n = N/Na
n=m/M
N=m total / m d'un seul
calculer la masse molaire (M)
M=Na x m nucléon (pas sur)
M= m/n
M= Cm/C
M= Na x m
calculer la masse d'un atome : 
m(atome)= (a(nbre nucléon) x 
m(nucleon)) (xNa) si une mole

Calculer le volume molaire :
  n = v/vm
  vm=V/n
  V=n x Vm
Calculer la concentration ( c):
n= C x v 
c = n/v 
v= n / c
Calculer concentration massique :
  Cm = C x M
  M=Cm/C
  C = Cm/M
  Cm = masse soluté / volume
  soluté 
  Si la masse n'est pas donné
  on utilise : 
    concentration molaire :
    n = c x v 
  concetration massique
  m = Cm x V
  Densité 
  d= rho(donné/rho(eau)-> 1000g/l
      rho= d( donné) x rho(eau)
      donc
      m= rho x V ( donné)
