M,etena=28g/mol=28kg/kmol
nCH2=CH2---> -[CH2-CH2-]n
28kg................................28kg
56kg..............................m,teor= 56kg
m,practic= 56x80/100kg=44,8kg
M,clorura de vinil= 62,5kg/kmol
nCH2=CH2----> nCH2=CHCl nCH2=CHCl=====> -[CH2-CHCL-]n
28kg....................62,5kg....................................................62,5kg
56kg.............................................................................m,teor= 125kg
m,practic= 125x80/100kg=100kg
