\(CTPT\left(A\right):C_xH_y\)
Theo đè bài ta có :
\(n\left(C\right):n\left(H\right)=\dfrac{81,81}{12}:\dfrac{18,18}{1}=6,82:18,18=1:2,66=3:8=x:y\)
\(\Rightarrow CTPT\left(A\right):\left(C_3H_8\right)_n\)
\(d\left(A/H_2\right)=22\Rightarrow M\left(A\right)=22.2=44\)
\(\Rightarrow44n=44\Rightarrow n=1\)
Vậy \(CTPT\left(A\right):C_3H_8\)
\(CTCT\left(A\right):\)
