Serial Dilution Questions
1, Serial dilution Questions: a) (5 pts) Suppose you begin with stock solution of dye that has a concentration of 350.0 mg/L and do the following set of serial dilutions on it: 5.00 mL of stock diluted to a total volume (TV) of 500.00 mL (Dilution 1); 2,00 mL of Dilution 1 is then diluted to a TV of 250.00 mL (Dilution 2); finally, 1.00 mL of Dilution 2 is then diluted to a total volume of...
The hint was: might need to do a serial dilution as outr
pipettes cannit dispense less than 2 microL.

b. 1 ml 1ml 「-I Final dilution 4(1 point) This represents a serial dilution to determine viable bacterial counts. Indicate the final dilutions in each of the two tubes. Note that two different volumes of the cells intube #2 are plated onto agar plates A and B. Indicate the dilution factor that will be used to report the original cell concentration on a per mL basis. 1 ml 1 ml Final dilution in Tube #1 = Final dilution in Tube...
Use stock solution of 0.5 M CuSO4 to make up the following solutions by serial dilution to a final volume of 1 ml: 50mM, 5mM, 0.5mM, and 0.05mM Please show 'how many DI water 0.5M CuSO4 needed to be used?'

Explain this example of the following water quality serial dilution. Note the dilution factors and how you would calculate #;s from the incubated plates. A serial dilution yielded TBTC in the 1:1 plate and the 1:10 plate, 10 cfu’s in the 1:100 plate and 1 cfu’s in the 1:1000 plate. What is the concentration (CFU)/ml of the raw sample? Is water acceptable for portable or Recreational use? Explain. When do you use your filtration rather than serial dilution?
In lab you carried out a serial dilution and calculated the concentration of each solution. Starting with a 2.05 M HCl stock solution, three standard solutions are prepared by sequentially diluting 5.00 mL of each solution to 150.0 mL. What is the concentration of the final solution? 0.0683 M 2.28 times 10^-3 M 9.11 times 10^-6 M 7.59 times 10^-5 M 2.53 times 10^-6 M
Molarity/Serial Dilution 1. What is the molar mass of (NH2)2NO3? 2. If I have 122g of (NH2)2NO3. how many moles? 3. I dissolve 112.0 grams of Na,Co, into 150 mL of water what is the molarity of the solution? 4. I have a 2.0 M of HCl, if I need to make a 2.5 liters of 0.1 M HCl how many milliliters of 2.0 M HCl will I need?
Draw (or describe) a dilution scheme for making the following bacteriophage titer plates: 1:100 (10-2), 1:1000 (10-3), and 1:10,000 (10-4) using a maximum of 2 dilution blanks. Show (or include in your description) all of the volumes including transfers, amounts in tubes and amounts plated.
