Ta có: \(n_Y=\dfrac{2,24}{22,4}=0,1\left(mol\right)\)
\(\Rightarrow M_Y=\dfrac{1,32}{0,1}=13,2\left(g/mol\right)\)
→ Y gồm H2 dư và C2H6.
\(\Rightarrow\left\{{}\begin{matrix}n_{H_2\left(dư\right)}+n_{C_2H_6}=0,1\\2n_{H_2\left(dư\right)}+30n_{C_2H_6}=1,32\end{matrix}\right.\) \(\Rightarrow\left\{{}\begin{matrix}n_{H_2\left(dư\right)}=0,06\left(mol\right)\\n_{C_2H_6}=0,04\left(mol\right)\end{matrix}\right.\)
Gọi: \(\left\{{}\begin{matrix}n_{H_2}=x\left(mol\right)\\n_{C_2H_2}=n_{C_2H_4}=y\left(mol\right)\end{matrix}\right.\)
BTNT C: 2y = 0,04 ⇒ y = 0,02 (mol)
Có: nH2 (pư) = 2nC2H2 + nC2H4 = 0,06 (mol)
⇒ nH2 = 0,06 + 0,06 = 0,12 (mol)
\(\Rightarrow V=\left(0,12+0,02+0,02\right).22,4=3,584\left(l\right)\)
