B. You will need approximately 1 ml of the 100 µg/ml bromophenol blue (which is your most concentrated standard) to generate your standard curve. Calculate how much bromophenol blue stock solution and how much water you will combine to accomplish this. Make 1 ml of this solution using a 100-1000 µl micropipetter. Use the equation C₁V1=C₂V2 μl of 1 mg/ml stock + μl of water = 1 ml of 100 µg/ml bromophenol blue

You have been provided with stock solutions of: stock A:     0.06 M sodium pyrophosphate buffer pH 8.5 stock B:     3 M ethanol stock C:     0.015 M NAD+ stock D:     milli Q water Determine the volume you will need of each solution to prepare a buffer of with a final volume of 60 mL containing 10 mM sodium pyrophosphate pH 8.5, 100 mM ethanol, 1 mM NAD+. i.e. volume of stock A = _________mL volume of stock B = _________mL volume of stock C = _________mL volume of stock D = _________mL Show your calculations to arrive at your answers.

1) You have been asked to make up four 1.5% agarose gels at 30 ml each. Ethidium Bromide is to be added at 0.5 ug/ml and you have a bottle at 10ug/ml. Write down step-by-step protocol of how to proceed.    2. How would you make up one liter of 1X TAE buffer using a 25X stock?

Digitalis, a drug used to control atrial fibrillation in patients is to be delivered to have a the drug amount to 20.0 μμg/kg body weight (2.205 pounds = 1.00 kg).  The drug concentration must be carefully controlled and accurately measured or the patient may die from too low of concentration from heart complications or too high concentrations of fatal overdose.  Calculate the mL of digitalis needed to treat a 160.0 pound patient using 0.800 mg/mL digitalis solution.

How many mLs should be removed from your dextrose 70% bag?

Gastric acid pH can range from 1 to 4, and most of the acid is HCl. For a sample of stomach acid that is 1.71x10-2 M in HCl, how many moles of HCl are in 14.0 mL of the stomach acid? Express the amount to three significant figures and include the appropriate units. ▸ View Available Hint(s) μ amount of HCI = Value Submit Units ?

Highlight your values of A,B,C and D.  For your question: A mL of B mol/L sodium phosphate solution is combined with C mL of  D mol/L calcium bicarbonate.  (Calcium bicarbonate is soluble.) A       mL B      mol/L C       mL D      mol/L 75.0 ml 0.300 67.5 0.350   Before you begin your reaction, you must accurately produce 1.500 L of your sodium phosphate solution from sodium phosphate trihydrate solid.  Write out a procedure to explain all the steps you will take in the lab when making the solution to ensure that your solution concentration is accurate.  Please include calculations that show the required mass of solid.  Also include the correct names of all equipment used.

The doctor ordered Oxacillin 650mg every 6 hours.  The instructions on the 2gm vial states to reconstitute with powder with 11.5ml of sterile water for injection, yielding 220mg/1.5ml. How many ml will you administer? using dimensional analysis and show work

Demonstrate the procedure for arriving at the answer. A. It is necessary to carry out baths with Amitraz 12.5% in a batch of 25 patients. The product label says to dilute 1.5 ml of the product in 1 liter of water, for this there is a 50-liter water tank to prepare the product. Each patient corresponds to 1.2 L of the product diluted in water for an effective treatment. Calculate: a) total ml of amitraz needed to make the dilution in the water tank. b) ml of the product for each patient. c) Total ml of diluted Amitraz for the batch of patients. Answer: R: a) 75 ml. b) 1200 ml. c) 30.000 ml (Ctrl)-
