`O_2` and He are taken in equal weights in a vessel. The pressure exerted by Helium in the mixture is 

A

`1/8^(th)` of total pressure

B

`1/9^(th)` of total pressure

C

`2/9^(th)` of total pressure

D

`8/9^(th)` of total pressure

Text Solution

Verified by Experts

`P_1 = (n_1)/(n_("Total")) cdot P = (w//4)/(w//4 + w//32) xx P = 8/9 P`.
