Metilena=4*MH+2*MC=4+2*12=28 g/mol
Malcool(etanol)=2*MC+6*MH=2*12+6=30 g/mol
Reactia este mol la mol, adica nu mai sunt si alti coeficienti la egalare =>
n=V/Vm=m/M=> 448/22.4=20moli=malcool/Malcool=> 20=m/30=> m=600g alcool

22,4L...............................46g
CH2=CH2 + HOH -> CH3-CH2-OH
448L..............................x=?
x=448*46/22,4=920g alcool etilic
CH2=CH2 + HOH -> CH3-CH2-OH

x=448*46/22,4=920g alcool etilic
