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))= 8.75 P(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= nRT`
`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))`
