Ta có: \(n_{Br_2}=0,03.1,5=0,045\left(mol\right)\)
PT: \(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)
___0,045__0,045 (mol)
Có: \(V_{C_2H_2}=V_{C_2H_4}\Leftrightarrow n_{C_2H_2}=n_{C_2H_4}=0,045\left(mol\right)\)
PT: \(C_2H_2+2Br_2\rightarrow C_2H_2Br_4\)
___0,045___0,09 (mol)
\(\Rightarrow V_{ddBr_2}=\dfrac{0,09}{1,5}=0,06\left(l\right)=60\left(ml\right)\)
