\(2C_3H_6+9O_2\rightarrow6CO_2+6H_2O\)
\(2C_2H_6+7O_2\rightarrow4CO_2+6H_2O\)
a, Ta có:
\(n_{CO2}=\frac{56}{22,4}=2,5\left(mol\right)\)
\(hh:C_3H_6:a\left(mol\right);C_2H_6:b\left(mol\right)\)
\(\left\{{}\begin{matrix}42a+30b=36\\3a+2b=2,5\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}a=0,5\\b=0,5\end{matrix}\right.\)
\(V_{C3H6}=V_{C2H6}=0,5.22,4=11,2\left(l\right)\)
b,\(\%V_{C3H6}=\%V_{C2H6}=50\%\)
