Electrochemistry and mole fraction

[fervent pecan]

I know there is going to be some use of the nernst equation and the mole fraction equation but just how I am not getting it

Que no. 45 : )

this is a conc cell. you know emf, right?
so you get the ratio of H+ cathode:anode

once you have that, you get pressure of H2 in the H2 + Ar mixture

and from that the mole fraction :) cos total pressure is given to be 1 atm

From the nernst equation right ?

Alright lemme try once
