1. MC2H5Cl = 64,5g/mol
MC2H4Cl2 = 99g/mol
64,5x+99y...................................35,5x+71y
100.................................................67,62
6694,388y+4361,49x = 3550x+7100y <=> 811,49x = 405,612 => x/y = 1/2
2. C2H4 + HCl ---> C2H5-Cl
C2H4 + Cl2 ---> C2H4Cl2
3. C2H4 + HCl ---> C2H5-Cl
n C2H5-Cl = n HCl = 2 moli
m HCl = 2*36,5 = 73g
C2H2 + HCl -> H2C=CH-Cl + HCl --> C2H4Cl2
nHCl = 2n C2H4Cl2 = 2*2 = 4 moli HCl
m HCl = 4*36,4 = 146g
