Equivalent conductivity, ∧eq=( text specific conductance × 1000/ text concentration (in g text equiv/L)) ∵ Specific conductance =(1/ text specific resistance ) (Given, concentration =C g equiv/L) ∴ ∧ eq =(1/R) × (1000/C) or =(1000/R C)

Q. A solution of concentration $C g$ equiv/L has a specific resistance $R .$ The equivalent conductance of the solution is

$\frac{R}{C}$

$\frac{C}{R}$

$\frac{1000}{RC}$

$\frac{1000 R}{C}$

Equivalent conductivity,
$\land_{e q} = \frac{specific conductance \times 1000}{concentration (in g equiv/L )}$
$∵$ Specific conductance
$= \frac{1}{specific resistance}$
(Given, concentration $= C g$ equiv/L)
$∴ \land_{e q} = \frac{1}{R} \times \frac{1000}{C}$
or $= \frac{1000}{RC}$
