- Hexanoic acid was added to an immiscible biphasic solvent sysem, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D1) of hexanoic acid in CCl4 with respect to water.Really hoping for solutions since I’m having a hard time with this. Pls. skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced. When the compounds analyzed by Robrob were passed on to the next test, anotherscientist, Kikoko, needed to determine the molecular weight of the active compound. They created a solution with a concentration of 20.0%w/w from the solid active compound and the solution had a density of 1.40 g/mL. From this solution, 10μL was taken and mixed with 190μL of reagent and water. It was analyzed and showed a concentration of 5x10-4 M compound.a. What is the concentration (in molarity) of the 20%w/w solution? b. Why was the concentration of the solution expressed as %w/w initially? c. What is the molecular weight of the active compound?order the PE and PET and lexan interm of Tg and explain why ? and give application on each one
