\(n_{CO_2}=\dfrac{13.44}{22.4}=0.6\left(mol\right)\)
\(n_{H_2O}=\dfrac{14.4}{18}=0.8\left(mol\right)\)
\(n_O=\dfrac{18.4-0.6\cdot12-0.8\cdot2}{16}=0.6\left(mol\right)\)
\(n_C:n_H:n_O=0.6:1.6:0.6=3:8:3\)
CT đơn giản nhất : C3H8O3
\(M_X=46\cdot2=92\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow92n=92\)
\(\Rightarrow n=1\)
