Question

The resistance of $0.01 M$ NACl solution is $200 o h m$ . The cell constant of conductivity cell is unity. Calculate the molar conductance.

Open in App

Solution

$κ$ = $\frac{c e l l c o n s t a n t}{R}$

$κ$ = $\frac{1}{200}$
$\land_{m}$ = $κ$ $\frac{1000}{M}$

$\land_{m}$ = $\frac{1000}{0.01 * 200}$

$\land_{m}$ = 500 $S c m^{2} m o l^{- 1}$
