Gọi \(\left\{{}\begin{matrix}n_{CH_4}=x\\n_{H_2}=y\end{matrix}\right.\)
\(n_{O_2}=\dfrac{7,437}{24,79}=0,3mol\)
\(n_{H_2O}=\dfrac{7,2}{18}=0,4mol\)
\(CH_4+2O_2\rightarrow\left(t^o\right)CO_2+2H_2O\)
x 2x x 2x ( mol )
\(2H_2+O_2\rightarrow\left(t^o\right)2H_2O\)
y 1/2 y y ( mol )
Ta có:
\(\left\{{}\begin{matrix}2x+\dfrac{1}{2}y=0,3\\2x+y=0,4\end{matrix}\right.\) \(\Leftrightarrow\left\{{}\begin{matrix}x=0,1\\y=0,2\end{matrix}\right.\)
\(m=m_{CH_4}+m_{H_2}=\left(0,1.16\right)+\left(0,2.2\right)=2g\)
\(V_{CO_2}=0,1.24,79=2,479l\)
