  • The conductivity of centimolar solution <img alt="\mathrm{KCl}$ at $250^{\circ} \mathrm{C}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7BKCl%7D%24%20at%20%24250%5E%7B%5Ccirc%7D%

The conductivity of centimolar solution \mathrm{KCl}$ at $250^{\circ} \mathrm{C} is 0.0210 \mathrm{ohm}^{-1} \mathrm{~cm}^{-1} and resistance of the cell containing the solution at 25^{\circ} \mathrm{C} is 60 ohm. The value of cell cons is -
 

Option: 1

1.34 \mathrm{~cm}^{-1}
 


Option: 2

3.28 \mathrm{~cm}^{-1}


Option: 3

1.26 \mathrm{~cm}^{-1}


Option: 4

3.34 \mathrm{~cm}^{-1}
