319089 A solution of x moles of sucrose in 100 g of water freezes at \({\rm{ - 0}}{\rm{.2^\circ C}}\). As ice separates the freezing point goes down to \({\rm{0}}{\rm{.2}}{{\rm{5}}^{\rm{^\circ }}}{\rm{C}}\). How many grams of ice would have separated?

319090 Assertion :
Molecular mass of polymers cannot be calculated by using boiling point or freezing point method.
Reason :
Polymer solutions possess a low boiling point or freezing point.
