is 0.0861 M![E_{cell}=E^o_{cell}-\frac{2.303RT}{nF}\log \frac{1}{[X]}](/tpl/images/0370/3205/84cb9.png)
= standard electrode potential of the cell = ?
= emf of the cell = 0.0460 V
![0.0610=0.124-\frac{2.303\times (8.314)\times (298)}{1\times 96500}\log \frac{1}{[X]}](/tpl/images/0370/3205/50159.png)
