A solution containing 62 g ethylene glycol in 250 g water is cooled to –10ºC. If K f for water is 1.86 K kg mol –1 , the amount of water (in g) separated as ice is:
Text Solution
Verified by ExpertsThe correct answer is:
D
Let x gram water is separated out
Δ T f = K f m
10 = 1.86 × 
or , 2500 – 10x = 1860
or , 10x = 640
or , x = 64 g.
