1. Serial Dilutions www.kent.ac.uk/student-learning-advisory-service

2. Serial dilutions Serial dilutions Introduction Calculating the quantity of a solution that contains the same amount of substance as different strength solution Bio/chem/pharm students

3. Serial dilutions Serial dilutions What volume of a 10% v/v solution contains the same amount of ingredient as 200mL of a 25% v/v solution? 1). Use C1V1 = C2V2 percentages cancel percentages cancel 25% 200?? = 10% ? ?? transpose and solve transpose and solve ? =25 200 = 500?? 10

4. Serial dilutions Serial dilutions Or What you want, over what you have What volume of a 80% v/v solution contains the same amount of ingredient as 240mL of a 5% v/v solution? 1). What you want, over what you have 5 240 80 = 15??

5. Serial dilutions Serial dilutions A formula asks for 1.6L of a 15% v/v solution. You only have 40% v/v solution. How much should you use? Answer: 600??

6. Serial dilutions Serial dilutions What volume of a 1 part in 500 w/v solution contains the same amount of ingredient as a 200mL of a 6mg/5mL solution? convert both to percentages convert both to percentages 0.006? 5?? 0.12? 100?? = 0.12% 500=0.2 1 & = 100 = 0.2% then then 0.12 200?? 0.2 = 120??

7. Serial dilutions Serial dilutions What volume of a 40mg/L solution contains the same amount of ingredient as 10mL of a 0.002% w/v solution? Answer: 5??
