Step 1
In this case, the final volume is 40 ml and the dilution factor is 1/100, so the initial volume can be calculated as follows: Initial volume = final volume / dilution factor Initial volume = 40 ml / 1/100 Initial volume = 40 ml * 100 Initial volume = 4000 ml Show more…

You have 5 ml of an overnight culture (2x10^8 cells per ml). How would you prepare a series of 1 or 10 ml dilutions (maximum dilution 1:100) to obtain a final 200 ml culture at 1x10^3 cells/ml? Provide work for each step.

Suppose someone starts a broth culture of E. coli at an initial concentration of 5,000 cfu/mL. How much sterile saline will someone have to mix with 1 mL of culture to get a 1/25 dilution of the culture?
What volume of 0.100 $\mathrm{M} \mathrm{NaOH}$ is required to neutralize 25.00 $\mathrm{mL}$ of 0.110 $\mathrm{M} \mathrm{H}_{2} \mathrm{SO}_{4} ?$
