Calculate Molarity for Each Trial
Calculate Molarity for Each Trial
You will need to calculate the molarity of the original concentrated HCl unknown for each trial (remember the steps from the rough titration). Once you have determined the molarity for each trial find, the average molarity for all three trials.

After determining your average molarity, calculate the percent difference for each trial. Determine if your data is precise enough. For this experiment, all data points used for determining the concentration should have a percent difference less than 4%. It is worth noting that the limit for "good" precision varies depending on the experiment. For some experiments the acceptable percent difference might be less than 1%, whereas the acceptable value for another experiment might be greater than 10%. Based on whether your data is precise enough, click the corresponding button below.
All trials have a 4% difference or less.
One or more trials have a percent difference of 4% or more.
