Gọi cthc: \(C_xH_yCl_z\) ; \(x,y,z\in Z^+\)
\(x:y:z=\dfrac{12x}{23,8}=\dfrac{y}{5,9}=\dfrac{35,5z}{70,3}=\dfrac{50,5}{100}\)
\(\Rightarrow x:y:z=1:3:1\)
Vậy cthc: \(CH_3Cl\)
b) PTK: \(\dfrac{1}{2}.32=16\)
Gọi cthc: \(C_xH_y\) ; \(x,y\in Z^+\)
\(x:y=\dfrac{12x}{75}=\dfrac{y}{25}=\dfrac{8}{100}\)
\(x:y=1:4\)
Vậy cthc: \(CH_4\)
a)gọi công thức hóa học là:\(C_xH_yCl_z\)
\(\Rightarrow\)x:y:z=\(\dfrac{23.8}{12}=\dfrac{5.9}{1}=\dfrac{70.3}{35.5}\)
\(\Rightarrow\)x:y:z=2:6:3
\(\Rightarrow\)công thức là \(\left(CH_3Cl\right)_2\)
