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) .
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 ).
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) ).
15 g of an unknown molecular substance was dissolved in 450 g of water. The resulting solution freezes at - 0 . 34^(@) C . What is them molar ass of the substance ? ( K_(f) for water = 1. 86 K kg mol^(-1) )
In winter, the normal temperature in a Himalayan's valley was found to be - 10^(@) C . Is a 30% by mass of an aqueous solutions of ethylene glycol (molar mass = 62) suitable for car radiator ? K_(f) for water is 1. 86 Km^(-1)
A motor vehicle radiator was filled with 8L of water to which 2 L of methyl alcohol (density 0.8g/mL) were added. What is the lowest temperature at which the vehicle can be parked outdoors without a danger that water in the radiator will freeze? K_f of water = 1.86Km^-1 .
