Solution

The correct option is A $390.7$ .
Using the given data,

${Λ^{\infty}}_{H O A c} = {Λ^{\infty}}_{N a O A C} + {Λ^{\infty}}_{H C l} - {Λ^{\infty}}_{N a C l}$

$= 91.0 + 426.2 - 126.5$ ${c m}^{2} {m o l}^{- 1}$

$= 390.7 S$ ${c m}^{2}$ ${m o l}^{- 1}$

The correct option is A 390.7.Using the given data,Λ∞HOAc=Λ∞NaOAC+Λ∞HCl−Λ∞NaCl =91.0+426.2−126.5 cm2mol−1 =390.7 S cm2 mol−1

The correct option is A $390.7$ .
Using the given data,

${Λ^{\infty}}_{H O A c} = {Λ^{\infty}}_{N a O A C} + {Λ^{\infty}}_{H C l} - {Λ^{\infty}}_{N a C l}$

$= 91.0 + 426.2 - 126.5$ ${c m}^{2} {m o l}^{- 1}$

$= 390.7 S$ ${c m}^{2}$ ${m o l}^{- 1}$
