125g x g
----------------- -------------------
CH3-CH2-Cl + H2O ---> CH3-CH2-OH + HCl
------------------- -----------------
64,5g 46g
x= (125*46)/64,5 = 89,14 (ct)
Dar avem si un randament
Randament = (Cp/Ct)*100 => Cp = (80*ct)/100 = 80*89,14/100 = 71,312g
Deci cantitatea de etanol ( alcool etilic ) obtinuta este de 71,312g
M clorura de etil = 15 + 14 + 35,5 = 64,5 g/mol
M alcool etilic = 15 + 14 + 17 = 46 g/mol
