  2 calculer PCO
M(C12H26)=12*12+26*1=170g/mol
M(O2+3.76N2)=2*16+3.76*(2*14)=137.28g
      C12H26+18.5(O2+3.76N2)
Mcarb=170g   18.5*137.28=2539.68g=Mair
PCO=Mair/Mcarb
PCO=2539.68/170=14.94
PCO=14.94

  pour richesse 1 calcul masse et volume 
  pour 1T de CO2 rejete
M(CO2)=12+2*16=44g/mol
C12H26        ->12CO2
170g            12*44=528g
178g de kerozene=528g de CO2
                =10**6g=1T de CO2
m=10**6*170/528=0.322T

0.322T de kerozene 
kerozene=liquide donc masse volu
densite=0.8
0.8kg=1kg
322kg=V
V=322*1/0.8=402.5L
402.5L consomme

  4 deduire que 3.44L/passager pour 100km
1 aller retour=2*5850km=11700km
402.5L=11700km
      =100km
402.5*100/11700=3.44L/passager/100km
