Answer:
1/1000 or 0.001
Explanation:
Serial dilution refers to the systematic dilution of the known concentration through successive suspension of initial volume to a fixed value of diluent.
In the given question, the serial dilution is performed in which the dilution factor will be
DF= volume of added solution / total volume of solution
For tube A
= 1/ 1+9
=1/10 or 10 folds.
For tube B
= 1/10 x 1/10
= 1/100 or 0.01
For Tube C
= 1/10 x 1/10 x 1/10
= 1/1000 or 0.001
Therefore, total dilution of tube C will be 0.001 or 1/1000.
