Answer:
dilution = 2.5*10^6
Explanation:
Given:
- Number of colonies N = 100 cfu
- The Volume of cells = 25*10^7 cells / ml
Find:
the final dilution
Solution:
- The expression relating the the colonies forming unit with cells//volume is given as:
Bacteria/ml = cfu*dilution
dilution = Volumetric cells/ cfu
dilution = 25*10^7 / 100
dilution = 2.5*10^6
