Level of solution
rises in the thistle
funnel due to
osmosis of solvent 45 g of ethylene glycol (C2H6O2) is mixed with 600 g of water Calculate
(a) the freezing point depression and (b) the freezing point of the solution Depression in freezing point is related to the molality, therefore, the molality
of the solution with respect to ethylene glycol =
moles of ethylene glycol
mass of water in kilogram
Moles of ethylene glycol =
