d=M/M,C2H2
M= 1,73X26=>45g.mol
1,8g compus.........1,792l CO2......0,440 LN2......2,52gH2O
45G.............................X.................................Y........................Z
X=44,8l CO2----> niuC= niuCO2= V/Vm= 44,8/22,4=> 2mol
y=11,2 l---> niuN2= V/Vm=11,2/22,4=> 0,5mol-> niuN=2niuN2=1mol
z=63gH2O--> niuH2O=m/M= 63/18-> 3,5mol niuH=2niuH2O=7mol
compusul este C2H7N
in 45g compus....24gC......7gH.......14gN
100g......................x....................y.............z
X=53,3%C
Y=15,6%H
Z= 31,1%N
