The amount of ice that will separate out on cooling a solution containing 50g of ethyleneglycol in 200g water to -9.3°C is K, of 11,0 -1.86°mol-'kg) |
|
Answer» Here, depression in freezing point ∆ T f = 9 . 3 0 C , here mass of glycol = 50 gm, then mass of water W =delta Tf =Kf*mm is the molality of the solutiondelta Tf is the depresion in freezing point9.3=1.86*50*1000/w*62w=161.29 gmHence, the mass of ice separated from water = 200 -161.29 =38.71 gm |
