in a cold climate water gets frozen causing damage to the radiator of a car . Ethylene glycol is used as an antifreezing agent . Calculate the amount of ethylene glycol to be added to 4kg of water to prevent it from freezing at `-6^@`C . (`K_f` for water 1.85`Km^-1`).

Calculate the amount of KCl which must be added to 1 kg of water so that its freezing point is depressed by 2 K.

How many grams of ethylene glycol (molar mass = 62) should be added to 10 kg of water, so that the resulting solution freezes at -10^(@)C ( K_(f) for water = 1.86 K "mol^(-1) ).

45g of ethylene glycol (C_2H_6O_2) is mixed with 600 g of water. Calculate: the freezing point of the solution. (K_f for water=1.86K kg mol^-1) .

Calculate the amount of ice that will be separate out on cooling a solution containing 50 g of ethylene glycol in 200 g of water to -9.3^@C . (K_f for water=1.86 Km^-1)

In cold concentries, a solution of water and ethylene glycol is used as coolant in an automobile engine radiator instead of water. Explain

The temperature of a city was found to be -9.3^(@) C. A car used, whose rasiator was filled with 5 L of water . What minimum quantity of antifreezing agent ethylene glycol were added to water of raiator in order to use the car for teavelling? ( K_(f) of water 1.86 k mol^(-1))
