A solution prepared by dissolving $65g$ of unknown compound in $500g$ of water boils at $105C.$ The

unknown compound produces three particles when dissolved in water. What is the molar mass of the unknown

compound? $K_b=0\mathrm{.}51\frac{C}{m},$ and boiling point of pure water $=100C.$

$65$

What is the freezing point of a solution containing $476g$ of ethylene glycol $(C_2{H}_6{O}_2$;$MW=62\mathrm{.}01\frac{g}{m}ol)$

in $3202g$ water?

A solution is formed by dissolving $70\mathrm{.}0g$ of $CuS{O}_4$ in $500\mathrm{.}0g$ of $H_{2}O.$ What is the freezing$-$point depression?

$K_f$ for water is $1\mathrm{.}86\frac{C}{m}.$
