C1:
\(m_C=\dfrac{136.88,235}{100}=120\left(g\right)=>n_C=\dfrac{120}{12}=10\left(mol\right)\)
\(m_H=136-120=16\left(g\right)=>n_H=\dfrac{16}{1}=16\left(mol\right)\)
=> CTPT: C10H16
C2:
%H = 100% - 88, 235% = 11,765%
Xét mC : mH = 88,235% : 11,765%
=> 12.nC : nH = 88,235 : 11,765
=> nC : nH = 7,353 : 11,765 = 5 : 8
=> CTPT: (C5H8)n
Mà M = 136
=> n = 2
=> CTPT: C10H16
