A solution containing 62 g enthylene glycol in 250 g water is cooled to -10°C. IfKffor water is 1.86 K kgmol-1, the amount of water (in g) separated as ice is

Options:

Answer:
D
Solution:

ΔTf=kf×WBMB×1000WA
WA(calculated=kfΔTf×WBMB×1000
ΔTf=Tf°-Tfs=0-(-10)=10
⇒WA=1.8610×6262×1000
=186 g
Amount of ice separated=250-186=64 g
