500 51. For the strong electroytes $\mathrm{NaOH},\mathrm{NaCl}$ and ${\mathrm{BaCl}}_2$ the molar ionic conductivities at infinite dilut are $240\times 10^{-4},125\times 10^{-4}$ and $280.0\times 10^{-4}{\mathrm{mho}}^2{\mathrm{mol}}^{-1}$ respectively. Calculate the $\mathrm{mo}$ conductivity in $\left({\mathrm{mho}}^2{\mathrm{mol}}^{-1}\right)$ of $\mathrm{Ba}(\mathrm{OH}{)}_2$ at infinite dilution. $\mathrm{ECO}26$ 52. Molar conductance of ${\mathrm{BaCl}}_2,{\mathrm{H}}_2{\mathrm{SO}}_4$ and $\mathrm{HCl}$ at infinite dilutions are $300{\Omega }^{-1}{\mathrm{cm}}^2/\mathrm{mole}$, $800{\Omega }^{-1}{\mathrm{cm}}^2/\mathrm{mole}$ and $400{\Omega }^{-1}{\mathrm{cm}}^2/$ mole respectively. Equivalent conductance of ${\mathrm{BaSO}}_4$ at infin dilution is. (in $\mathrm{S}-{\mathrm{cm}}^2/\mathrm{eq}$.) EC0266 53. Equivalent conductance of $0.01\mathrm{N}{\mathrm{Na}}_2{\mathrm{SO}}_4$ solution is $120{\mathrm{ohm}}^{-1}{\mathrm{cm}}^2{\mathrm{eq}}^{-1}$. The equivale conductance at infinite dilution is $150{\mathrm{ohm}}^{-1}{\mathrm{cm}}^2{\mathrm{eq}}^{-1}$. What is the degree of dissociation in 0.01 ${\mathrm{Na}}_2{\mathrm{SO}}_4$ solution? 54. The value of ${\Lambda }_{\mathrm{m}}^{\infty }$ for $\mathrm{HCl},\mathrm{NaCl}$ and ${\mathrm{CH}}_3{\mathrm{CO}}_2\mathrm{Na}$ 5 and $100\mathrm{Scm}$ EC020 the equivalent conductivity of $\mathrm{A}$ given acetic acid degree of dissociation. $m^2$ equivalen: spectively. calculate degree of dissociation. 55.
