Chemistry - Liquid Solution Question with Solution | TestHub

$20\%$ of acetic acid is ionized when its 5 g is added to 500 mL of water. The depression in freezing point of such water is $\_\_\_\_$ $\times 10^{-3}{}^{\circ }\mathrm{C}$. Atomic mass of $\mathrm{C},\mathrm{H}$ and 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 $1\mathrm{g}{\mathrm{cm}}^{-3}$ respectively.
