Ta có: \(n_{CH_4}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
PT: \(CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
Theo PT: \(n_{O_2}=2n_{CH_4}=0,4\left(mol\right)\)
\(\Rightarrow m_{O_2}=0,4.32=12,8\left(g\right)\)
\(PTHH:2CH_4+O_2\rightarrow2CO+4H_2\)
\(2:1:2:4\left(mol\right)\)
\(0,2:0,1:0,2:0,4\left(mol\right)\)
\(n_{CH_4}=\dfrac{V}{22,4}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
\(m_{O_2}=n.M=0,1.\left(16.2\right)=3,2\left(g\right)\)
