F.g. hidrocarbura aromatica saturata-> CnH2n-6=14n-6
14n-6=106==>14n=112=>n=8 -> F.m C8H10 -> etilbenzen
C6H6 + CH2=CH2 ---> C8H10
C8H10 ---> C6H5-CH=CH2 (vinilbenzen)
C6H5-CH=CH2 ----> -[-C6H5-CH-CH2-]-n
b) MC8H8=104kg...........................104kg polimer

moonlight01:
ai raspuns ?
oops :)
era astfel: n=mp/mt*100==>mt=mp*100/n=52*100/78=66,666kg polimer.. 106kg C8H10........................104kg C8H8.........66,666kg C8H8.............x=66,666*106/104=67,94871kg C8H10.... 78kg C6H6...................106kg C8H10.....67,94871kg..............x=78*67,94871/106=50kg C6H6....1kg=1000g => 50*1000=50000g C6H6 => ro=m/V=>V=m/ro=50000g/0,88g/cm3=56811,181818cm3/1000=56,818181L C6H6...
