If you go back and try this exercise again the values will change. Read the question carefully! Answer:Please answer the PHYSICAL DESCRIPTION table and add short captions for the photos. THANK YOU.
- Can you please provide steps for how to answer the following? This is not a graded assignment, it's just practice questions for no credit. The concentration of the stock glucosamine solution is 100 mM. A student took 0.5 ml of this stock solution and added it to a test tube containing 24.5 ml of water. The student then took 1 ml out of the diluted solution and added it to another test tube containing 9 ml of water. The concentration of glucosamine in the second test tube will be: a. 0.4 mM b. 0.8 mM c. 1.2 mM d. 1.6 mM e. 0.2 mM. If you took 10 ml out of a protein stock solation of 0.25 mg/ml and added it to a bottle containing 40 ml of buffer and 500 ul of cofactor. What will be the final concentration of the protein in the bottle? a. 55.5 ug/ml b. 45.5 ug/ml c. 52.5 ug/ml d. 49.5 ug/ml e. 65.5 ug/mlQuestions 15 through 20 pertain to the following medication formula: Here is the formula a pain and inflammation reducing ointment.

Weight of Tween in milligrams. 18. Weight of Span, in milligrams. 19. Weight of Polypeg base, in grams. 20. What is the final concentration of methyl salicylate, as a percent concentration (w/w)?Biological studies have found that aqueous solutions containing as little as 28 µg of allicin per milliliter inhibit bacterial growth.

- If you are performing a solvent extraction using 1M HCl (Density slightly > 1.00 g/mL) and diethyl ether (density = .706 g/mL) which layer is the aqueous layer? which is the bottom and top layer?Find # 20-#23 with the provided dataHi! I need answers for numbers 2 and 3. My professor said that The unit of solubility is in grams per 100mL, while the solvent used is only 50mL, so a yield of close to 2.0g is impossible. Recalculate using this information. Thanks!
