PT: \(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)
Ta có: \(n_{C_2H_4Br_2}=\dfrac{28,2}{188}=0,15\left(mol\right)\)
Theo PT: \(n_{C_2H_4}=n_{Br_2}=n_{C_2H_4Br_2}=0,15\left(mol\right)\)
\(\Rightarrow\left\{{}\begin{matrix}\%V_{C_2H_4}=\dfrac{0,15.22,4}{5,6}.100\%=60\%\\\%V_{CH_4}=40\%\end{matrix}\right.\)
\(m_{Br_2}=0,15.160=24\left(g\right)\)
