Answer:
Step 1. 1:100
Step 2. 1:1000
Step 3. 1:100,000
Explanation:
At first step, 0.1 ml is diluted in 9.9 ml of saline. Multiple both with 10 you will get 1 ml in 99 ml suggesting total dilution at first step as 1:100.
At second step, 1 ml of 100x dilution will be taken and further dissolved in the 9 ml of B3. Here, the dilution factor is further 10 times therefore the total dilution would be 1:1000.
At third step, 0.01 ml would be taken from 1000x dilution and further diluted in 9.99 ml. Therefore, the dilution factor here is 100 times. Hence the final dilution at this stage would be 1:100,000.
This is the simplest explanation I can give.
Hope it helps.
