हिन्दीThe conductivity of centimolar solution of \( \mathrm{KCl} \) at \( 25^{\circ} \mathrm{C} \) is \( 0.0210 \text{ ohm}^{-1} \text{ cm}^{-1} \) and the resistance of the cell containing the solution at \( 25^{\circ} \mathrm{C} \) is \( 60 \text{ ohm} \). The value of cell constant is -
Correct answer · Option 4
\( 1.26 \text{ cm}^{-1} \)
Explanation
Cell constant \( (\frac{l}{A}) = \text{Conductivity } (\kappa) \times \text{Resistance } (R) = 0.0210 \times 60 = 1.26 \text{ cm}^{-1} \).
