Ta có: \(n_{Br_2}=\dfrac{8}{160}=0,05\left(mol\right)\)
PT: \(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)
_____0,05____0,05 (mol)
\(\Rightarrow V_{C_2H_4}=0,05.22,4=1,12\left(l\right)\)
\(V_{CH_4}=5,6-1,12=4,48\left(l\right)\)

C2H4 + Br2 ---------->C2H4Br2
nBr=m/M=8/160=0,05 (mol)
VC2H4=n.22,4= 0,05. 22,4=1,12(lít)
