Câu 17:
\(1.\) Đặt CTHH là \(C_xH_yO_z\)
\(\%_O=100\%-40\%-6,67\%=53,33\%\\ \Rightarrow x:y:z=\dfrac{40}{12}:\dfrac{6,67}{1}:\dfrac{53,33}{16}=3,33:6,67:3,33=1:2:1\\ \Rightarrow CTDGN:\left(CH_2O\right)_n\)
\(2.\) Ta có \(M_{\left(CH_2O\right)_n}=2,143\cdot14\cdot2=60=30n\)
\(\Rightarrow n=2\)
Vậy \(CTHH_X:C_2H_4O_2\)
Câu 16:
