1. A solution is known to contain 38.04 ± 0.03 mM KCl, and you have taken analiquot of this solution using a pipette calibrated to deliver 20.013 ±0.006 mL.Determine the number of moles of KCl that are delivered in the aliquot, includingthe absolute uncertainly in that value.2. You deliver the aliquot taken in problem 1 into a volumetric flask with a volume of250.00 mL ± 0.02 % and dilute the solution to volume in the flask using Dl water.What is the concentration of KCl in this flask, report your answer with the absoluteuncertainty.3. Tabulated below are replicate titration volumes for an analysis. What is the error(both absolute and percent) for the average titration volume?

Concentration of KCl = Volume of KCl = The number of moles can be determined using the equation,…
