Answer to Question #178777 in Chemistry for Karley Eilts

Question

What is the boiling point elevation of an aqueous solution of sucrose with a molal concentration of 1.35 m?

Answer 1

deltaT = K_bm

where:

       deltaT is the change in the boiling point of the solvent,

        K_b is the molal boiling point elevation constant (for water K_b=0.512^oC⋅m^-1)

        m is the molal concentration of the solute in the solution.

deltaT = 0.512⋅1.35 = 0.69^oC
