The resistance of conductivity cell with cell constant 1 . 14   cm - 1 , containing 0 . 001 M  …

The resistance of conductivity cell with cell constant 1.14 cm-1, containing 0.001M KCl at 298 K is 1500Ω. The molar conductivity of 0.001M KCl solution at 298 K in S cm2 mol-1 is (Integer answer)

Solution

k=1R×ℓA=11500×1.14 S cm-1

⇒∧m=1000×1.1415000.001 S cm2 mol-1

=760 S cm2 mol-1⇒760
