You have a sample – sample 1 - that has a concentration (✗) particles. From this you take 1 mL and add it to 99 mL water to create sample 2. You then take 1 mL of sample 2 and place it in 99 mL of water to create sample 3. And lastly, you take 1 mL of sample 3 and add it to 9 mL of water to create sample 4. What is the final dilution factor in sample 4? You may use drawings if it helps you understand and explain, though not necessary.
