Răspuns:
V= 448dm³=448 l CH4 impur
p= Vpurx100/V impur= 448x80/100 l=358,4 lCH4 pur
niu=V/Vm= 358,4/22,4mol=16mol CH4
2mol............1mol
2CH4----> C2H2+ 3H2
16mol............x
x=niu=8mol acetilena ,cu randament 100%
La randament mai mic,seva obtine ma iputin
niu,practc= 8x80/100mol= 6,4molC2H2
V=niuxVm=6,4x22,4l=143,4l
