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…
My question is: Could you explain steps? (etc. why do we heat or add chemicals like nacl or ammonium sulphate?) 1)Casein Isolation from MilkExperimental Procedure* Put 100 ml of milk in a 500 ml beaker and heat it to 40 0C. * Also heat 100 ml acetate buffer and slowly add it to the beaker with milk while stirring. * The final pH of the mixture should be 4.8. * Cool the suspension to room temperature and wait 5 more minutes before filtering. * Wash the precipitate several times with small volumes of water and then suspend it in approximately 30 ml of ethanol.Filter the suspension in the buchner funnel and wash the precipitate a second time with a mixture of equal proportions of ethanol and ether. * Finally, wash the precipitate on filter paper with 50 ml of ether and soak and dry. * Make the ether evaporate by spreading the powder. * Weigh the casein and calculate the percentage yield of the protein. * Compare with theoretical yield of 3.5 g per 100 ml milk. 2)Purification of Egg…
If molecules are expected to move from high concentration to low concentration, why didn’t all the molecules (solutes) leave the dialysis tubing bag (the test solution was tested negative for one solute)
In this experiment, you are to prepare 250mL of Cell Lysis Buffer using the reagents given in Table. Fill out the table. Show your computations at the bottom of the table.
Gel-filtration chromatography separates molecules according to their size . Smaller molecules diffuse faster in solution than larger ones, yet smaller molecules migrate more slowly through a gel- filtration column than larger ones. explain this paradox. What should happen at very rapid flow rates?

A. a pre-weighted dialysis bag which contained a solution of 10% glucose was placed in a beaker which contained 20% glucose. After one hour, the bag was weighted again. Calculate the % mass change of the dialysis bag from the following information: Mass of bag before the experiment: 15.3g Mass of bag after the experiment: 12.7% B. was the beaker solution hypertonic, hypotonic, or isotonic?
