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/ml

30 20 10 From the procedure 2. Assemble the simple distillation apparatus as generally shown in Figure SD.1 in the lab manual, ensuring that the thermometer bulb is aligned at, or slightly below, the Y in the distillation head. Each ground joint is greased by putting three or four stripes of grease lengthwise around the male joint and pressing the joint firmly into the other without twisting. 3. Attach a water condenser to the distillation head. 4. Remember, water goes in the bottom and out the top. Attach a clamp holder to the end of the drain tube to keep it weighted in the drain. Turn water to a trickle. If it is slowly draining, it is high enough. Begin a low flow of water through the condenser. 5. Place the set up on a heating/stir plate. 6. Turn on the hot plate to start heating the solution. Monitor the temperature and the boiling of the solution throughout the distillation process. 7. Record the temperature of the distillate when the first drops are recovered. 30.0 8. Adjust…

Complete the table by entering the molarity of B2- for each standard solution. Show an illustrative calculation for tube ‘A’. Use the dilution formula and express each result to one more digit than allowed by applying the rules of significant figures. Standard Volume of stock B2- solution taken, mL Molarity of dilute B2 Construct a graph of Absorbance vs. molarity of B2- in Excel using the data in the preceding table. Make certain to title the graph and include axes labels with proper units. Absorbance is dimensionless (has no unit). Add a linear trendline to the graph but do not set the y-intercept to zero Solid M2B is added to 25 mL of water, the resulting mixture is continually stirred for 1 hour. At this point, it is assumed that equilibrium (eqn 3) has been established. The mixture is transferred to a test tube, and the test tube is centrifuged to assure that any residual solid M2B is fully settled out. A portion of the supernatant in the test tube is carefully…
