This is a molarity problem that I cannot figure out. If you could please help me understand the steps to solving it that would be greatly appreciated! Question: We need to prepare a stock solution of medium for your culture cells, which usually includes liquid salt solution and bovine serum. Our liquid salt solution is supplied in a 50X concentration, and we need to dilute it to 1X for use. We also need to add 75% fetal bovine serum for a final concentration of 15%. How would we make up 0.80 liters of this culture media using water as our solvent?

You will be given 1 mL of a 2.0 mg/mL solution of bovine serum albumin (BSA) and 1 mL of a 2.0 mg/mL solution of bovine gamma globulin (BGG). From these solutions, you will need to make 100 μL of each of the following standards using 1x MBP purification buffer as the diluent for preparation of a standard curve: 1000 μg/mL, 750 μg/mL, 500 μg/mL, 250 μg/mL, 125 μg/mL, and 0 μg/mL.
You have an order for 1 gram of Cefazolin in D5W 100 ml. You have added 5 ml of sterile water to the 1 gram vial to reconstitute powder. However the recommended manufacturer’s diluent amount is 10 ml of sterile water for a final concentration of 100 mg/ml. How would reconstituting the vial with 5 mls affect the concentration and the final calculated dose. Please answer with explanation ASAP. I will really upvote. Thanks
Determine the concentration of L. monocytogenes enumerated from the apple slice based on the information below. You must draw your serial dilution and show your mathematical calculation. The apple slice (12 g) was first mixed with 108 ml of sterile 0.1% peptone water. After, 1 ml was added to tube containing 9 ml of sterile 0.1% peptone water. Process was repeated with two additional tubes. 1 ml was pipetted from tubes 2 and 3 onto MOX media. Plates were incubated at 37 for 48 hours. The pictures below show the plates from tube 2 (left) and tube 3 (right).

Given this, if you used 6g of vitamin Z powder to make 20 ml of solution, what is the % concentration of this solution? (I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria. One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution. Given that each bacterial…
Question 1: Suppose you have given 5 tablets weighing 449mg, 450mg, 448mg, 451mg and 453mg, respectively. Calculate 300 mg equivalent sample weight for assay. The product claim is 500 mg Vitamin C is present in each tablet. Question 2: Volume of the standard sodium edetate is 12.6 mL (calculated after the assay of Zinc Sulfate Syrup). Determine the % of potency of the drug considering the claimed dose is 11.5
A series of bovine serum albumin (BSA) was prepared and 1 mL of each solution was subjected to a Bradford assay. The increase in absorbance at 595 nm relative to the concentration of protein was plotted as shown below. Save 1.0- 0.8- 0.6- 0.4- 0.2- 0.04 0.0 0.5 1.0 2.0 2.5 1.5 BSA concentration (mg/mL) a) Using the graph, calculate the original concentration of protein present in a mixture of haemoglobin and methylene blue (diluted 1:50), which gave an absorbance of 0.20 at a wavelength of 595 nm using the Bradford assay. Show all workings. Absorbance (O.D.)
The accompanying figure is from an electrophoresis experiment using SDS–PAGE. The left lane has the following standards: bovine serum albumin (MW 66,000), ovalbumin (MW45,000), glyceraldehyde 3-phosphate dehydrogenase (MW 36,000),carbonic anhydrase (MW 24,000), and trypsinogen (MW 20,000).The right lane is an unknown. Calculate the MW of the unknown.
Consider a batch culture of sphere-shaped bacteria in a growth medium or broth, in which the mean cell diameter of the bacteria is 2.0 μm (micron). Show all your calculations and assumptions in answering the questions below: What is the volume of one of these sphere-shaped cells, expressed in liters? If there are 3 x 10^12 cells in one liter of this culture broth, what percentage of the volume is occupied by bacteria and what percentage is occupied by the cell culture broth (water only)? If the cells contain 80% water, what is the dry cell concentration, expressed as “grams dry weight/Liter of broth”? You should assume that the density of the cells dry mass is approximately 1.0 gr/cm3
Explain how gel filtration chromatography works. What type of gel will you used when the protein size is 2500 Da? Explain.
4 mL of 10% TCA solution was added to 1 mL of serum and after mixing, it was waited for two minutes and filtered through non-phosphorus filter paper. 1 mL of the filtrate was taken and 13 mL of distilled water, 4 mL of sulfomolybdic acid and 2 mL of dilute SnCl2 solution were added and mixed, and after waiting for 15 minutes, the absorbances of the obtained solutions against pure water at 520 nm were read. If the function of the calibration graph obtained with 0.5-2.5 mg/mL standard phosphorus solutions is y= 0.245x + 0.107 and the absorbance value of the serum sample is 0.109, what is the amount of phosphorus in the sample?
