(C) Key Idea: Kohlrausch law of independent migration of ions can be used to calculate $\Delta_m^o$ for weak electrolytes such as acetic acid.Given:$\Delta_{m(NaAc)}^o = 91 \ S \ cm^2 \ mol^{-1}$$\Delta_{m(HCl)}^o = 425.9 \ S \ cm^2 \ mol^{-1}$$\Delta_{m(NaCl)}^o = 126.4 \ S \ cm^2 \ mol^{-1}$Using Kohlrausch law,the molar conductivity of acetic acid is calculated as:$\Delta_{m(CH_3COOH)}^o = \Delta_{m(CH_3COONa)}^o + \Delta_{m(HCl)}^o - \Delta_{m(NaCl)}^o$$= (91.0 + 425.9 - 126.4) \ S \ cm^2 \ mol^{-1}$$= 390.5 \ S \ cm^2 \ mol^{-1}$

For an $HCl$ solution at $25^o C$,the equivalent conductance at infinite dilution is $425 \ \Omega^{-1} \ cm^2 \ eq^{-1}$. The electrical conductivity of the $HCl$ solution is $3.825 \ \Omega^{-1} \ cm^{-1}$. If the degree of dissociation is $90\%$,what is the normality of the solution in $N$?
