Strategy:
 The cell constant () is a property of the electrodes and geometric container, independent of the electrolyte. Use the data from the first solution to find , then apply it to the second solution.

Step 1: Calculate Cell Constant ()
From  data: , .

Step 2: Calculate  for 
.

Nearest integer: 57.
