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

If the $K_f$ value of $H_2O$ is $1.86$,what is the value of $\Delta T_f$ for a $0.1 \ m$ solution of a non-volatile solute?

What will be the freezing point of a $1\%$ aqueous solution of $Ca(NO_3)_2$?

Which of the following aqueous solutions has the highest freezing point?

$31 \ g$ of ethylene glycol $(C_2H_6O_2)$ is dissolved in $600 \ g$ of water. The freezing point depression of the solution is ($K_f$ for water is $1.86 \ K \ kg \ mol^{-1}$) (in $K$)

In cold countries,ethylene glycol is added to water in the radiators to:
