Ta có: \(n_X=\dfrac{10,08}{22,4}=0,45\left(mol\right)\)
\(n_{C_2Ag_2}=\dfrac{48}{240}=0,2\left(mol\right)=n_{C_2H_2}\)
\(\Rightarrow m_{C_2H_2}=0,2.26=5,2\left(g\right)\)
\(n_{Br_2}=\dfrac{88}{160}=0,55\left(mol\right)=n_{C_2H_4}+2n_{C_2H_2}\)
\(\Rightarrow n_{C_2H_4}=0,55-0,2.2=0,15\left(mol\right)\)
\(\Rightarrow m_{C_2H_4}=0,15.28=4,2\left(g\right)\)
\(\Rightarrow n_{CH_4}=0,45-0,15-0,2=0,1\left(mol\right)\)
\(\Rightarrow m_{CH_4}=0,1.16=1,6\left(g\right)\)
