LAB 4: Experiment 4: Acid Neutralizing Potential of Antacids

acid solution: 225 mL of distilled water w/20 mL of 6 M HCl

base solution: 5.0 mL of the ~6.0 M NaOH solution into a 250 mL volumetric flask, diluted with water until we reached the volume mar

how do I calculate the percent error: % error = (theoretical - experimental) / (theoretical) x 100 from my three trials of titrations in the table above
