$Λ^{\infty} (S c m^{2} m o l^{- 1})$ 149.9 145.0 426.2 91.0 126.5

Calculate $Λ_{H O A C}^{\infty} (in S c m^{2} m o l^{- 1})$ using appropriate molar conductances of the electrolytes listed above at infinite dilution in $H_{2} O$ at $2 5^{\circ}$ C.

552.7

390.7

217.5

$\land$ $HOAC \infty$ = $\land$ $NaOAC \infty$ + $\land$ $HCl \infty$ - $\land$ $NaCl \infty$
= 91.0 + 426.2 - 126.5 S cm² mol^-1
= 390.7 S cm² mol^-1
