Chemistry - Liquid Solution Question with Solution | TestHub

Depression in freezing point is given as ${\mathrm{\Delta T}}_{\mathrm{f}}={\mathrm{K}}_{\mathrm{f}}\mathrm{m}$

Molality of solution $\left(\mathrm{m}\right)=\frac{{\mathrm{\Delta T}}_{\mathrm{f}}}{{\mathrm{K}}_{\mathrm{f}}}$

or $\mathrm{m}=\frac{0.6}{1.86}=0.322 \mathrm{m}$

Elevation in boiling point of solution is given as

${\mathrm{\Delta T}}_{\mathrm{b}}={\mathrm{k}}_{\mathrm{b}}\times \mathrm{m}$

${\mathrm{\Delta T}}_{\mathrm{b}}=0.512\times 0.322$

${\mathrm{\Delta T}}_{\mathrm{b}}=0.165$

$\therefore$ Boiling point of solution $=373+0.16$

$=373.16 \mathrm{K}$
