A vessel is filled with a mixture of oxygen and nitrogen. At what ratio of partial pressures will the mass of gases be identical.

A

`P_(O_2)= 0.785P_(N_2)`

B

`P_(O_2)= 8.75P_(N_2)`

C

`P_(O_2)= 11.4P_(N_2)`

D

`P_(O_2)= 0.875P_(N_2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`PV= (w)/(m)RT, P_(O_2)V= (w)/(32)RT, P_(N_2)V= (w)/(28)RT`
`(P_(O_2))/(P_(N_2))= (28)/(32)P_(O_2)= 0.875 P_(N_2)`.
