LABORATORY 10 DETERMINATION OF VITAMIN C CONCENTRATION 3. How many grams of (pure) vitamin C is contained in your unknown stock solution (Part A)? Hint: The solution is made in a 1-L bottle. 4. Consider the following titration: If 21.35 mL of 0.005 M iodine solution is needed to titrate a solution of commercial vitamin C tablet (500 mg) pre- pared in a 100-mL volumetric flask, then what is the mass (%) of vitamin C in the commercial tablet? 5....

Question 5 (0.5 points) If you added a enzyme to a protein sample in which the polymers were degraded into individual amino acids, what would you expect after adding Biuret reagent? OA) A deep violet purple color would be present B) Enzymes cannot be used to break down proteins C) There would be no reaction and thus no color change D) The color of the solution would reflect the concentration...

Results 3. (5 points) Our transformation procedure used 10 u of 0.08 ug/ul PGLO. How does the concentration of DNA affect the number of colonies and the transformation efficiency? Do you think if we used more concentrated PGLO that we could have gotten a higher transformation efficiency? The numbers of colonies shown below resulted from transformation with 10ul of PGLO at the concentrations shown. a. Calculate the transformation efficiency at each concentration. Express your answers in scientific notation. Write the...
