7. Consider the expression of Raoult's law, Psolution = Xsolvent ·P⁰solvent . Here, Psolution = vapor pressure of the solution, P⁰solvent = vapor pressure of pure solvent, Xsolvent = mole fraction of the solvent. What is the mole fraction of solvent in a solution with a vapor pressure of 47.90 torr, if the vapor pressure of the pure solvent is 52.82 torr? 8. The boiling point of a solution increases directly as a function of the number of moles of...

A solution of ethylene glycol in water at 20 degrees celsius has a mass percent of 9.78% of ethylene glycol with a density of 1.0108 g/mL. The freezing point depression constant for water (solvent for all solutions) is Kf=-1.86 percent celsius kg/mol and the boiling point elevation constant is Kb=0.512 degrees celsius kg/mol. The density of neat water at 20.0 degrees celsius is 0.9982 g/mL. Answer the following: 1. What is the molarity of the solution? 2. What is the...

Hello, I need help solving the 3 parts of this question.
Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As...
