Get started for freeA solution contains a mixture of pentane and hexane at room temperature. The solution has a vapor pressure of 258 torr. Pure pentane and hexane have vapor pressures of 425 torr and 151 torr, respectively, at room temperature. What is the mole fraction composition of the mixture? (Assume ideal behavior.)
An aqucous \(\mathrm{NaCl}\) solution is made using 112 \(\mathrm{g}\) of \(\mathrm{NaCl}\) diluted to a total solution volume of 1.00 \(\mathrm{L}\) . Calculate the molarity, molality, and mass percent of the solution. (Assume a density of 1.08 \(\mathrm{g} / \mathrm{mL}\) for the solution.)
Explain how the relative strengths of solute-solute interactions, solvent- solvent interactions, and solvent-solute interactions affect solution formation.
Water softeners often replace calcium ions in hard water with sodium ions. Because sodium compounds are soluble, the presence of sodium ions in water does not cause the white, scaly residues caused by calci- um ions. However, calcium is more beneficial to human health than sodium because calcium is a necessary part of to human diet, while high levels of sodium intake are linked to increases in blood pressure. The U.S. Food and Drug Administration (FDA) recommends that adults ingest less than 2.4 \(\mathrm{g}\) of sodium per day. How many liters of softened water, containing a sodium concentration of 0.050\(\%\) sodium by mass, docs a person have to consume to excecd the FDA recom- mendation? (Assume a water density of 1.0 \(\mathrm{g} / \mathrm{mL} .\) )
A solution is prepared from 4.5701 \(\mathrm{g}\) of magnesium chloride and 43.238 \(\mathrm{g}\) of water. The vapor pressure of water above this solution is 0.3624 \(\mathrm{atm}\) at 348.0 \(\mathrm{K}\) . The vapor pressure of pure water at this tem- perature is 0.3804 atm. Find the value of the van't Hoff factor \((i)\) for magnesium chloride in this solution.
