20 \%

of acetic acid is dissociated when its

5 \mathrm{~g}

is added to

500 \mathrm{~mL}

of water. The depression in freezing point of such water is

\underline{\hspace{2cm}}

\times 10^{-3}{ }^{\circ} \mathrm{C}

. Atomic mass of

\mathrm{C}, \mathrm{H}

and

\mathrm{O}

are 12,1 and 16 a.m.u. respectively. [Given : Molal depression constant and density of water are

1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}

and
