Problem

A mixture of ethane (

\text{C}_2\text{H}_6

) and ethene (

\text{C}_2\text{H}_4

) occupies 40 litre at 1.00 atm and at 400 K. The mixture reacts completely with 130 g of

\text{O}_2

to produce

\text{CO}_2

and

\text{H}_2\text{O}

. Assuming ideal gas behaviour, calculate the mole fractions of

\text{C}_2\text{H}_4

and

\text{C}_2\text{H}_6

in the mixture.
