A solution of water (Kf=1.86 ∘C/m) and glucose freezes at − 2.35 ∘C. What is the molal concentration of glucose in this solution? Assume that the freezing point of pure water is 0.00 ∘C. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) m m m = nothing nothing Submit Boiling points and molality Similar to the freezing-point depression, the boiling-point elevation ΔTb of a solution is quantitatively related to the molality m and the boiling-point-elevation constant Kb of the solvent by the equation ΔTb=Kbm where the boiling-point elevation is the difference between the boiling points of the solution and the pure solvent. Part C A solution of water (Kb=0.512 ∘C/m) and glucose boils at 102.56 ∘C. What is the molal concentration of glucose in this solution? Assume that the boiling point of pure water is 100.00 ∘C. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) m m m = nothing nothing
