The volume of the solution I am making is 2.5 L. To measure this volume I will use a large graduated cylinder that can measure volume to ± 10 mL. What is the absolute uncertainty in my concentration? 

• A. 0.0001 M
• B. 0.0100 M
• C. 0.4499 M
• D. 0.0002 M

Answer: (D)

Verified step by step guidance

1. Understand that the absolute uncertainty in concentration is related to the uncertainty in volume measurement.
2. Identify the volume of the solution, which is 2.5 L, and the uncertainty in the volume measurement, which is ± 10 mL.
3. Convert the uncertainty from milliliters to liters: 10 mL = 0.010 L.
4. Calculate the relative uncertainty in volume by dividing the absolute uncertainty by the measured volume: (0.010 L / 2.5 L).
5. Apply the relative uncertainty to the concentration to find the absolute uncertainty in concentration: multiply the relative uncertainty by the concentration value (e.g., 0.0001 M, 0.0100 M, 0.4499 M) to find the absolute uncertainty in each case.
