Answer: Intended dilution factor =  

and

Actual dilution factor =  

Explanation:

Given;

The intended added volume of the undiluted sample = 1.0 mL

The volume of the sterile diluent = 99 mL

The intended added volume = 5 mL

now,

the dilution factor is given as :

Dilution factor = (Volume added to the solution)/(Total volume of the solution )

thus,

the intended dilution factor =

or

Intended dilution factor =  1.0ml/1+99ml

also,

the actual dilution factor = 100

or 5.0ml/5+99ml

Actual dilution factor = 104

intended= 1x10^-2

actual= 4.8x10-2
