Answer:
CFU/mL
Explanation:
Given -
a) Number of colonies of bacteria is equal to 
b) Total volume of the solution is equal to
mL
c) Dilution factor is equal to 
As we know that
CFU/mL 
Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume
Substituting the given values in above equation, we get -
CFU/mL
