The resistance of a conductivity cell containing 0.001M KCl solution is 1500 ohm. What is the cell constant if conductivity of the solution at 298K is 0.000146 S/cm.

Given, 

Resistance (R) = 1500 ohm

Conductivity of solution = 0.000146 S/cm

We know that,

Conductivity = (1/Resistance) × Cell constant

Cell constant = Conductivity × Resistance

Cell constant = 0.000146 × 1500 =  0.219 cm-1
