Some nonelectrolyte solute (molar mass = 142 g/mol) was dissolved in 150. mL of a solvent (density = 0.879 g/cm3). The elevated boiling point of the solution was 355.4 K. What mass of solute was dissolved in the solvent? For the solvent, the enthalpy of vaporization is 33.90 kJ/mol, the entropy of vaporization is 95.95 J/K mol, and the boiling-point elevation constant is 2.5 K kg/mol.
Suppose that a solution made from an unknown solute dissolved in solvent X. Its molality is 0.0125 and it boils 0.047oC higher than solvent X's boiling point.

A solution is prepared by dissolving 40.00 g of MgCl2 (f.w. = 95.211 g mol–1), a non-volatile solute, in enough water (m.w. = 18.02 g mol–1) to result in exactly 2 L of solution at 25 °C. Assume the density of the solution is that of pure water (dsolution = 1.000 g mL–1). The ebullioscopic constant (Kb) for water is 0.513 °C m–1. The cryoscopic constant (Kf) for water is 1.86 °C m–1.

Consider the following two white solids below and their physical properties based on information gathered from the Merck Index: Camphor: melting point=179C; boiling point = 209C; sublimes (under vacuum); the solubility of camphor at 25C is listed as follows: to dissolve 1g of camphor: 800mL of ethanol; 1mL of ether. (Note: ethanol is miscible with water and with ether; ether is mot miscible with water). Cinnamic acid: melting point= 134C; heating above 146C causes the molecule to chemically change; the solubility of cinnamic acid at 25C is listed as follows: to dissolve 1g of cinnamic acid: 2,000mL of water; 6mLof ethanol; fully soluble in ether. based on the information above, would either of the following two methods be suitable to seperate camphor from cinnamic acid? explain your answer. a. Sublimination b. Distillation c. Treating a 2g mixture with 30mL of ethanol to selectively dissolve camphor and leaving cinamic acid behind.
Can you form a homogenous solution between ionic compounds like LiCl and vegetable oil? Why or why not? Explain your reasoning using thermodynamic equations or values to support your answer (hint: think of ΔHsolution = ΔHsolute + ΔHsolvent + ΔHmixture and the types of IMFs that can form between solute-solute, solvent-solvent, and solute-solvent particles. Also, it would be helpful to compare IMFs between solute-solute, solvent-solvent, and solute-solvent particles for water and vegetable oil as a solvent.

a) For a compound with a molecular weight of 130 g / mol, at a melting temperature of 425.15 K under 1 bar pressure, the solid and liquid phases have a density of 1100 and 1024 kg / m3, respectively. When the pressure is increased to 125 bar, the melting temperature rises to 427.45 K. Calculate the ΔSo and ΔHo values for this compound during the transition from solid to liquid phase.b) Explain why molality is preferred over molarity in applications of numerical (colligative) properties.
A friend of yours who is taking a biochemistry class saysthat salting out works because the waters of hydration thatsurround the protein prefer to surround the electrolyte asthe electrolyte is added; therefore, the protein’s hydrationshell is stripped away, leading to protein precipitation. Anotherfriend of yours in the same biochemistry class saysthat salting out works because the incoming ions adsorbtightly to the protein, making ion pairs on the protein surface,which end up giving the protein a zero net charge inwater and therefore leading to precipitation. Discuss thesetwo hypotheses. What kind of measurements would youneed to make to distinguish between these two hypotheses?
