Use the table of equipment uncertainty in the slides to calculate the percent uncertainty on a 500 mL volumetric flask. 15 % 0.0003 % 0.03 % 0.15 % Question 9 (0.25 points) A 25 mL pipette and a 500 mL volumetric flask were used to dilute the 0.2500 g/L Fe stock to prepare the primary standard iron solution. Use the percent uncertainties calculated in the previous two questions to calculate the percent uncertainty on the concentration of the primary standard iron solution (we calculated its concentration together; it was 12.50 mg Fe/L.) 0.08 % 0.26 % (0.3%)
