Ta có: \(n_{Br_2}=\dfrac{48}{160}=0,3\left(mol\right)\)
PT: \(C_2H_2+2Br_2\rightarrow C_2H_2Br_4\)
____0,15___0,3 (mol)
\(\Rightarrow\left\{{}\begin{matrix}V_{C_2H_2}=0,15.22,4=3,36\left(l\right)\\V_{CH_4}=2,24\left(l\right)\end{matrix}\right.\)
Bạn tham khảo nhé!
$C_2H_2+2Br_2\to Br_2CH-CHBr_2$
$n_{Br_2}=\dfrac{48}{160}=0,3(mol)$
$\Rightarrow n_{C_2H_2}=\dfrac{n_{Br_2}}{2}=0,15(mol)$
$\Rightarrow V_{C_2H_2}=0,15.22,4=3,36(l)$
$\Rightarrow V_{CH_4}=5,6-3,36=2,24(l)$
