Problem: Suppose you obtained the following data from doing the experiment described in the procedure. Complete the data table. The 25.00 mL of diluted HCI titrated in the experiments was prepared by diluting 25.00 mL of a stock solution to 250.00 mL in a volumetric flask. The stock solution is the undiluted HCI.
Concentration of NaOH = 0.120M
Trial 1
Trial 2
Trial 3
Initial buret reading
6.24 mL
0.50 mL
1.48
Final buret reading
26.06 mL
19.62 mL

Volume of NaOH added
Moles of NaOH added
Moles of HCI reacted
Molarity of diluted HCI
Molarity of undiluted HCI
Average molarity of undiluted HCI
1. Find the molarity of the original HCI stock. Show your work as outlined in the calculations.
2. Are these three titrations close enough so that another one need not be done? Use a calculation to explain your response.
