Which of the following aqueous molal solution have highest freezing point

Molal freezing point depression constant (K_(f)) may be calculated from the following thermodynamically derived equation

The Rast method, one of the older techniques for finding the molecular mass of an unknown, measures the freezing point depression of solution in camphor. Camphor is used because its freezing point is very sensitive to added solution solute (It has highest K_(f)) . A solution of 2.342 g of an unknown substancein 49.88 g of camphor freezes at 441.2 K . If K_(f) for camphor is 40.0 Kg mol^(-1) , calculate the molecular mass of the unknown. Strategy: Find the molality of the solution from the freezing point of the pure camphor, the freezing point of the solution and the value of K_(f) by using the relationship DeltaT_(f)=K_(f)m . From the molality, find the no. of moles of solute in given mass of solvent. Finally find the molar mass (Melting point of pure camphar is 453.0 K)

A system of greater disorder of molecules is more probable. The disorder of molecules is reflected by the entropy of the system. A liquid vapourizes to form a more disordered gas. When a solute is present, there is additional contribution to the entropy of the liquid due to increased randomness. As the entropy of solution is higher than that of pure liquid, there is weaker tendency to form the gas. Thus, a solute (non-volatile) lowers the vapour pressure of a liquid, and hence a higher boiling point of the solution. Similarly, the greater randomness of the solution opposes the tendercy to freeze. In consequence, a lower temperature must be reached for achieving the equilibrium between the solid (frozen solvent) and the solution. The elevation in boiling point (DeltaT_(b)) and depression in freezing point (DeltaT_(f)) of a solution are the colligative properties which depend only on the concentration of particles of the solute and not their identity. For dilute solutions, (DeltaT_(b)) and (DeltaT_(f)) are proportional to the molarity of the solute in the solution. A liquid possessing which of the following characteristics will be most suitable for determining the molecular mass of a compound by cryoscopic measurements?

For an ideal solution containing a non-volatille solute, which of the following expression is correct represented? where m is the molality of the solution and K_(b) is molal elevation constant.
