1/9
What is an example of a serial dilution?
1:10 to 1:100 to 1:1000
How would you obtain a 1:10 dilution?
0.1mL in 0.9mL
0.1mL = X microliters
X = 100 microliers
df
Dilution Factor
Formula to calculate dilution and cell number.
1/vol * 1/df * # colonies
0.02 mm^3 = X /cm^3
X = 5*10^4
1 cm^3 = X mL
X = 1mL
