Assuming that pentane and hexane form an ideal solution, A. Calculate the amount of pentane to be added to 65.0 g of hexane to obtain a minimum dG of mixing from mixing those two components. [MM pentane; 72.15, MM hexane; -86.18] B. Calculate the dS of mixing the components of the mixture above.
Boiling Point Elevation/Freezing Point Depression T = m K where, for freezing point depression: T = T(pure solvent) - T(solution) and for boiling point elevation: T = T(solution) - T(pure solvent) m = (# moles solute / Kg solvent) Kb = boiling point elevation constant. Kf = freezing point depression constant. Kb and Kf depend only on the SOLVENT. Below are some common values. Use these values for the calculations that follow.
