Em tham khảo nha:
\(\begin{array}{l}
1)\\
CTHH:{C_x}{H_y}{O_z}\\
x:y:z = \dfrac{{57,12}}{{12}}:\dfrac{{13,04}}{1}:\dfrac{{29,84}}{{16}} = 2:6:1\\
\Rightarrow CTDGN:{C_2}{H_6}O\\
MA = 46 \Rightarrow 46n = 46 \Rightarrow n = 1\\
\Rightarrow CTPT:{C_2}{H_6}O\\
VD1:\\
CTPT:{C_3}{H_9}{O_3}
\end{array}\)
