4) The molality of naphthalene in a solution of naphthalene (C₁oHs, MW= 128.18 g/mol) and cyclohexane (C6H12, MW = 84.16 g/mol) is my = 0.438 mol/kg. Using the information given below (given at p = 1.00 atm) find the normal melting point and normal boiling point of the solution T* = 6.6 °C (normal freezing point for cyclohexane) Kr=20.0 kg °C/mol (freezing point depression constant for cyclohexane) To* = 80.7 °C (normal boiling point for cyclohexane) Kb = 2.79 kg °C/mol (boiling point depression constant for cyclohexane)

Question
Transcribed Image Text:4) The molality of naphthalene in a solution of naphthalene (C10H8, MW= 128.18 g/mol) and cyclohexane
(C6H12, MW = 84.16 g/mol) is my = 0.438 mol/kg. Using the information given below (given at p = 1.00
atm) find the normal melting point and normal boiling point of the solution
T* = 6.6 °C (normal freezing point for cyclohexane)
Kr=20.0 kg °C/mol (freezing point depression constant for cyclohexane)
Tb* = 80.7 °C (normal boiling point for cyclohexane)
Kb = 2.79 kg °C/mol (boiling point depression constant for cyclohexane)
Expert Solution
Step 1: Colligative properties:
The colligative properties are those properties of solutions that depend on the number of solute particles, and not depend on the nature of the solute particles. The number of solute particles can be related to the molality of the solution. These properties depend on the nature of the solvent.
