For the following problem indicate the values for each part of the equation and solve for the unknown value: Peter adds 200 μL of bacteria to a tube containing 2 mLs of nutrient broth and then adds 300 μL of a certain disinfectant. The final concentration of the disinfectant in this tube after adding it is 5%.

On the graph that relates absorbance to flavin concentration, draw a horizontal line that starts at the point on the y-axis that corresponds to the absorbance of your unknown sample and ends at the curve you drew through your data points . Next draw a vertical line that starts at the point where the horizontal line intersected the curve and ends at the x-axis. The point where this vertical line intersects the x-axis corresponds to the concentration of flavin in your unknown sample. What was the letter on the tube with your unknown sample? What is the concentration of the flavin in your unknown

A patient is prescribed Cipro for an upper espiratory tract infection. The oral suspension is labelled 200 mg/5 mL and the patient needs to take 800 mg every 12 hours for 7 to 15 days.  How many ug are in each dose? How many mL must the patient take in each dose? How many g of Cipro is the patient taking every 24 hours? What is the molarity of the Cipro oral suspension? MW Cipro=331.35 g/mole

Briefly describe how you would make 500 mls of a 1X electrophoresis running buffer from a 15X stock solution.
