The correct Answer is:
4
Let us denote oxygen gas by 1 and hydrogen gas by 2.
Here, `(P_1)/(P_2) = 4/1`
As particle pressure of a gas in a mixture is the pressure it would exerts for the same volume and temperature, if it alone occupied the vessel therefore for common `V` and `T`
`P_(1) V = mu_(1)RT` and `P_(2)V = mu_(2)RT`
`therefore (mu_1)/(mu_2) = (P_1)/(P_2) = 4/1`.
