\(n_{H_2}+n_{C_4H_{10}}=\dfrac{V}{22,4}=\dfrac{17,92}{22,4}=0,8\left(mol\right)\)
Gọi số mol \(C_4H_{10}\) là \(x\left(mol\right)\)
Số mol \(H_2\) là \(3x\left(mol\right)\)
Ta có : \(3x+x=0,8\)
\(\Rightarrow4x=0,8\\ \Rightarrow x=0,2\\ \Rightarrow n_{C_4H_{10}}=0,2\left(mol\right)\\ \Rightarrow n_{H_2}=3\cdot0,2=0,6\left(mol\right)\\ \Rightarrow V_{C_4H_{10}}=n\cdot22,4=0,2\cdot22,4=4,48\left(l\right)\\ V_{H_2}=n\cdot22,4=0,6\cdot22,4=13,44\left(l\right)\\ \Rightarrow\%C_4H_{10}=\dfrac{4,48}{17,92}\cdot100=25\%\\ \%H_2=\dfrac{13,44}{17,92}\cdot100=75\%\)
