If an aqueous solution of glucose is allowed to freeze,then crystals of which substance will be separated out first?

Which of the following will show maximum depression in freezing point when the concentration is $0.1 \ M$?

If molality of the dilute solution is doubled,the value of molal depression constant $(K_f)$ will be

$A$ $5 \%$ solution (by mass) of cane sugar in water has a freezing point of $271 \, K$. Calculate the freezing point of a $5 \%$ glucose solution in water,given that the freezing point of pure water is $273.15 \, K$.

What is the unit of cryoscopic constant?

For water,$K_f = 1.86 \ K \ kg \ mol^{-1}$. If your car radiator contains $1.0 \ kg$ of water,how many grams of ethylene glycol $(C_2H_6O_2)$ must be added to lower the freezing point of the solution to $-2.8 \ ^\circ C$?
