Please find your section below. You will be provided a new data set which includes a fourth trial.
Determine the molarity of the original concentrated HCl solution from the fourth trial. Excluding the outlier from the first three trials (in other words, do not use the trial with ≥4% difference in your second analysis), recalculate the average molarity and percent differences for your new data set. Is your data set more or less precise than the first one?
When you are finished analyzing your data, proceed to the next section.
