Chemistry - Mole Concept Question with Solution | TestHub

In a gaseous mixture an alkane $\left({\mathrm{C}}_{\mathrm{x}}{\mathrm{H}}_{2\mathrm{x}+2}\right)$ and an alkene $\left({\mathrm{C}}_{\mathrm{y}}{\mathrm{H}}_{2\mathrm{y}}\right)$ are taken in $2:1$ mole ratios, the average molecular weight of mixture is observed to be 20 . If the same alkane and alkene are taken in $1:2$ mole ratios, the average molecular weight of mixture is observed to be 24 . Then the value of ' $x$ ' and ' $y$ ' respectively are :
