A conductivity cell filled with 0.1 M solution of KCI registers a resistance of $25.0\mathrm{\Omega }$ . If the cell constant of the cell is $0.25{\mathrm{cm}}^{-1}$, the conductivity of the solution would be

Conductivity of the solution is $\kappa =\frac{K_{\mathrm{cell}}}{R}=\frac{0.25{\mathrm{cm}}^{-1}}{25.0\mathrm{\Omega }}=0.01\mathrm{S}{\mathrm{cm}}^{-1}$.

An aqueous solution's conductivity is a measurement of its electrical current-transfer capacity. The conductivity rises with the concentration and mobility of ions in the solution as well as the water's temperature because ions carry the current.
