What is the boiling point of a 0.32-molal solution of iodine (I₂) in benzene at 1 atm?
Strategy

Use the value of kb for benzene given in Table 12.4 and the molal concentration of the solute to find the change of the boiling point of the solution. This change must be added to the normal boiling point of the solvent.
