Equal mass of methane and oxygen are mixed in an empty container at `25^(@)`C. The fraction of the total pressure exerted by oxygen is:

A

`(1)/(3)`

B

`(1)/(2)`

C

`(2)/(3)`

D

`(1)/(3) xx (273)/(298)`

Text Solution

Verified by Experts

The correct Answer is:
A
`P_("total") = X_(O_(2)) P_(O_(2)), (P_("total"))/(P_(O_(2)))=` fraction of total pressure exerted by `O_(2)`
