Gọi cthc: \(S_xO_y\) ; x, y \(\in Z^+\)
\(x:y=\dfrac{50}{32x}:\dfrac{50}{16y}\)\(\Rightarrow x:y=1,5625:3,125\)
\(\Rightarrow x:y=1:2\)
Vậy cthc: \(SO_2\)
2. \(\%_C=100-14,29=85,71\%\)
\(X=16.1,3125=21\left(g\right)\)
Gọi cthc: \(C_xH_y\) ; x, y \(\in Z^+\)
\(x:y=\dfrac{12x}{85,71}=\dfrac{y}{14,29}=\dfrac{21}{100}\)
\(\Rightarrow x:y=1,5:3\)
\(\Rightarrow x:y=1:2\)
Vậy cthc: \(CH_2\)
