Răspuns:
caclculez masele de C,H si N care se gasesce in 0,45g compus si apoi cele care se gasesc in 100g compus
miu,CO2=44g/mol
44gCo2.........12gC
0,88g.................x
x=mC= 0,24gC
miu.H2O=18g/mol
18gH2O...........2gH
0,63g...............x
x=0,07gH
miu,N2=28g/mol
Vm=22,4 l/mol
22,4 l...........28gN2
0.112 l.............x
x=m,N2=0,14 gN2
0,45gcompus.......0,24gC........0,07gH.......0,14gN2
100G...........................X.................Y.......................Z
X=53,33% C
Y=15,55%H
Z= 31,11%N2
