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

`P_(O_(2)) = 0.785 P_(N_(2))`

`P_(O_(2)) = 8.75 P_(N_(2))`

`P_(O_(2)) = 11 , 4 P_(N_(2))`

`P_(O_(2)) = 0.875 P_(N_(2))`

Text Solution

Verified by Experts

The correct Answer is:

`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)) `
