Q. The molar conductivities of $K Cl, N a Cl$ and $K N O_{3}$ are $152, 128$ and $111 S c m^{2} m o l^{- 1}$ respectively. What is the molar conductivity of $N a N O_{3}$ ?

$101 S c m^{2} m o l^{- 1}$

$87 S c m^{2} m o l^{- 1}$

$- 101 S c m^{2} m o l^{- 1}$

$- 391 S c m^{2} m o l^{- 1}$

difference = $24 S c m^{2} m o l^{- 1}$
Molar conductivities of $K NO - 3 = 111$
Molar conductivities of $N a N O_{3}$
$= 111 - 24 = 87 S c m^{2} m p l^{- 1}$
