A solution containing $\displaystyle 62$ g ethylene glycol in $\displaystyle 250$ g water is cooled to $\displaystyle -10^{\circ} \mathrm{C}$. If $\displaystyle \mathrm{K}_{\mathrm{f}}$ for water is $\displaystyle 1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$, the amount of water (in g) separated as ice is :
Official answer
(4)
$\displaystyle 64$
