There's a lot of work has to be done by you

doing \(\Rightarrow\)done

\(n_{CO_2}=\dfrac{6,72}{22,4}=0,3mol\Rightarrow m_C=3,6g\)

\(n_{H_2O}=\dfrac{7,2}{18}=0,4mol\Rightarrow n_H=0,4\cdot2=0,8\Rightarrow m_H=0,8g\)

Nhận thấy: \(m_C+m_H=4,4=m_A\)

\(\Rightarrow A\) chỉ chứa hai nguyên tố C và H.

Gọi CTHH là \(C_xH_y\).

\(\Rightarrow x:y=n_C:n_H=0,3:0,8=3:8\)

\(\Rightarrow C_3H_8\)

Gọi CTĐGN là \(\left(C_3H_8\right)_n\)

Mà \(M=44\)g/mol\(\Rightarrow44n=44\Rightarrow n=1\)

Vậy CTPT là \(C_3H_8\)
