Chemistry - Electrochemistry Question with Solution | TestHub

The formula for conductivity $k$ is given by:

$k=\frac{\text{Cell constant}}{R}$

Given:
Cell constant $=0.9{\text{ cm}}^{-1}$
Resistance $R=6530\Omega$

Substituting the values into the formula:

$k=\frac{0.9}{6530}$

$k=1.378\times 10^{-4}{\Omega }^{-1}{\text{ cm}}^{-1}$

$k\approx 1.38\times 10^{-4}{\Omega }^{-1}{\text{ cm}}^{-1}$

Answer: $1.38\times 10^{-4}{\Omega }^{-1}{\mathrm{cm}}^{-1}$
