Standard solution: 2.50M HCl
Unknown solution: NaOH
Four titrations were completed. In each case, 20.0 mL of acid were used. The results of each trial are shown below, including the volume of NaOH used.
Trial # ----------------- NaOH added (mL)
1 --------------------- 26.4
2 ----------------------22.0
3 ----------------------21.8
4 ----------------------22.0
a.) Excluding trial one, calculate the average molarity of the NaOH solution. (Show a formula, set-up, proper label, and round to the correct number of sig-figs.
