\(n_{CO2}=\frac{1,12}{22,4}=0,05\left(mol\right)\)
\(n_{H2O}>n_{CO2}\Rightarrow X:anken\)
\(n_{anken}=n_{H2O}-n_{CO2}=0,06-0,05=0,1\left(mol\right)\)
\(M_{anken}=\frac{0,72}{0,01}=72\left(\frac{g}{mol}\right)\)
\(14n+2=72\Rightarrow n=5\)
Vậy CTPT là C5H12
nCO2=1,12\22,4=0,05mol
nH2O>nCO2=>X:anken=nH2O−nCO2=0,06−0,05=0,01mol
Manken=0,72\0,01=72g/mol
14n+2=72=>n=5=>CTPT:C5H12
