Solution

Kohlrausch law of independent migration of ions:
$Λ_{m}^{0} = λ_{+}^{0} + λ_{-}^{0}$

$λ_{+}^{0} \to Limiting molar conductivities of cation$
$λ_{-}^{0} \to Limiting molar conductivities of anion$

Using the given data,
$Λ_{H N O_{3}}^{0} = Λ_{K N O_{3}}^{0} + Λ_{H C l}^{0} - Λ_{K C l}^{0}$
$Λ_{H N O_{3}}^{0} = 145.0 + 426.2 - 149.9$
$Λ_{H N O_{3}}^{0} = 421.3 S c m^{2} {mol}^{- 1}$

$Λ_{H O A c}^{0} = Λ_{N a O A C}^{0} + Λ_{H C l}^{0} - Λ_{N a C l}^{0}$
$Λ_{H O A c}^{0} = 91.0 + 426.2 - 126.5$
$Λ_{H O A c}^{0} = 390.7 S c m^{2} {mol}^{- 1}$
