Given : $\left(\mathrm{K}_{\mathrm{r}}\right)_{\text {water }}=1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$.
density of acetic acid is $1.2 \mathrm{~g} \mathrm{~mol}^{-1}$
molar mass of water $=18 \mathrm{~g} \mathrm{~mol}^{-1}$.
molar mass of acetic acid $=60 \mathrm{~g} \mathrm{~mol}^{-1}$.
density of water $=1 \mathrm{~g} \mathrm{~cm}^{-3}$
Acetic acid dissociates as
$\mathrm{CH}_3 \mathrm{COOH} \rightleftharpoons \mathrm{CH}_3 \mathrm{COO}^{\oplus}+\mathrm{H}^{\oplus}$
${\lambda _{NaCl}} = 38.2\;oh{m^{ - 1}}\,c{m^2}\,gme{q^{ - 1}}$,
${\lambda _{HCl}} = 203\;oh{m^{ - 1}}\,c{m^2}\,gme{q^{ - 1}}$,
What is the value of ${\lambda _{ClC{H_2}COOH}}$ .............. ${\rm{Oh}}{{\rm{m}}^{ - 1}}{\mkern 1mu} {\rm{c}}{{\rm{m}}^2}{\rm{gm}}\,{\rm{e}}{{\rm{q}}^{ - 1}}$
