The following image is a scheme for serial dilutions prepared for spectrophotometric analysis. If the stock solution concentration is 0.05 % (v/v) can you calculate the other tube’s concentrations in % v/v? I've used this with direct dilutions, how would I use this on serial dilutions?
You have prepared the following serial dilution using tryptone broth:d1: 0.1ml culture + 9.9 ml brothd2: 300µl d1 + 4.7 ml brothd3: 0.2ml d2 + 9800 µl broth1) Write your dilutions as a rational number AND in scientific format? What was your total dilution (in scientific notation)?2) What was the original concentration of your culture if you spread 0.1 ml of d3 and counted360 cfu?
A sample is diluted by a factor of 10 five times. The 10^-3 dilution has 272 colonies on it. Assuming you plated the same volume on each plate, how many colonies would you expect to find on the 10^-2 plate? Include units and use OCD formula.
Can you please explain how the cultures and the control mechanism for each quadrant of the plates work on the picture? Thank you

The following are errors that people commonly make when they perform serial dilutions. Indicate whether you think that the number of cfu/ ml calculated would be too high or too low if you make this mistake. You intend to add 0.9 ml of diluent to each tube and 0.1 ml of culture. Instead, you add 0.5 ml of diluent to each tube and 0.1 ml of culture to the first tube. Then, you make a serial dilution of 0.1 ml into and from each tube as described. You prepare 0.9 ml of diluents in each tube. You add 0.1 ml of culture (from the overnight culture provided) to every tube. You add 0.9 ml of diluent to each tube. You add 0.1 ml of culture to the first tube and mix. You get distracted, and transfer 0.1 ml to the third tube instead of the second. You perform the rest of the series as described.
How do you calculate the initial concentration of a sample? How would you make a 1:10 dilution of a broth culture if the final volume of the dilution is 10 ml? How much broth, and how much diluent, would you add? If you made a series of tenfold dilutions, exactly the same way as you described in question 1, what would be the dilution factor in the fifth tube?
