Ammonium alum 800 g Sodium carbonate 1000g Peppermint Oil 0.01% (0.01 g/100mL) Sodium benzoate 0.1% (0.1 g/100mL) Purified water, qs ad. 2000 mL a. 0.06 g b. 30 g c. 24 g d. 0.006 gYou are given 150 mL of an oil made up of a mixture of 3 fatty acids: palmitoleic acid (C 16:1 (n-7)) erucic acid (C 22:1 (n-9)) stearidonic acid (C 18:4 (n-3)) You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid. Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3. The densities of the individual fatty acids are: palmitoleic acid = 0.894 g/cm3 erucic acid = 0.860 g/cm3 stearidonic acid = 0.9334 g/cm3 Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?Rank the amino acids used in the experiment in Part II in the order of increasing solubility in water(mobile phase) Phe(0.4), Ala(0.5), Gly(0.8), Ser (0.9), Lys (0.6) and Asp(0.8).

A flowchart of the experiment is included as well. Thank you.Create a Schematic Diagram Delivering an aliquot and dilution1. Using a serological pipette, transfer accurately a 10-ml aliquot of the previously prepared NaCl solution into a 100-ml volumetric flask, then dilute to mark using distilled water.2. Put a stopper on the volumetric flask. Then invert the glassware up and down around five times, making sure there are no leaks.3. Put the diluted solution in a reagent bottle, then properly label the solution. Note the concentration of the solution. Show your reagent bottle to your instructor for checking.Erwin Smith wants to determine the average concentration of amino acids present in the spinal fluid of Eldians.
