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?

00:01 First of all, let's summarize the problem with the help of the scheme.
00:05 So we have a stock suspension of a shrihyr goli with concentration of 5 ,000 colony forming units per militer.
00:16 And we make the dilution 1 to 25 by adding 1 militer of the bacterial culture.
00:25 And we have to calculate the volume of sterile saline solution that must be used for this dilution...
