A mixture of methane and ethylene in the volume ratio `x : y` has a total volume of 30 ml . On complete combustion it gave 40 ml of `CO_(2)` . If the ratio had been `y :x` , instead of `x : y` , what volume of `CO_(2)` could have been obtained ?

A

`1:1`

B

` 1: 2`

C

` 2: 1`

D

`3:1`

Text Solution

Verified by Experts

The correct Answer is:
C
If volume of `NH_4OH ` = xml
then HCl = ` ( 300 -x ) ml`
pH of mixture = ` pKa of NH_4^(+) `
`rArr " buffer with " [S] =[B]`
` 1 xx ( 300 - x) = ( 1 xx x ) - ( 300 -x ) `
` rArr x = ( 600)/( 3 ) = 200 rArr " ratio " =(200)/(100) = (2)/(1) `
