Question

1 mole of a non-volatile non-dissociative solid solute is dissolved in 200 moles of water. The solution is taken to a temperature T_K (lower than freezing point of solution) to cause ice formation. After removal of ice the remaining solution is taken to 373 K where vapour pressure is observe to be 740 mm of Hg. Identify the correct options:
Given Data: K_f (H2O) = 2K kg mol^-1 and normal boiling point of H2O = 373 K.
