Question

Alchena a carei masa creste cu 32,14% prin aditia apei este?

Answer 1

CxH2x + H2O = CxH(2x+1)O
  M                        M+18
M+18 = 132,14/100 ·M
0,3214M = 18    M = 56g/mol    14x = 56    x = 4      C4H8

Answer 2

CnH2n+HOH=>CnH(2n+1)-OH
CnH(2n+2)O
∆m=14n+18-14n=18 g
∆m/M×100=32,14=>M=56 g/mol
14n=56
n=4
C4H8
