What is the conductivity of 0.02 M AgNO 3 solution having cell constant $1.1 \mathrm{~cm}^{-1}$ and resistance is 94.5 ohms?
  1. $0.0216 . \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}$
  2. $0.0116 \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}$
  3. $0.0416 \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}$
  4. $0.0859 \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}$

Solution

$\begin{aligned} \text { Conductivity }(\mathrm{k}) & =\frac{\text { Cell constant }}{\mathrm{R}} \\ & =\frac{1.1 \mathrm{~cm}^{-1}}{94.5 \mathrm{ohms}} \\ & =0.0116 \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}\end{aligned}$
