Question

5g of ethylene glycolis mixed with 600g of water.Ccalculate freezing point depression

Answer 1

Depression in freezing point =Kf×m

where Kf is the cryoscopic constant of water and m is the molality of ethylene glycol solution.

delta Tf= 1.86×(55×1000/62×600) =1.4785

Hence, new freezing point=273-1.4785 =271.521K
