5. A student prepared and standardized a NaOH solution. He then used this NaOH solution to determine the molar concentration of an acid using a titration procedure. The results were calculated from five separate titrations as reported below. Calculated Results Titration # Molar Concentration of Acid 0.550 M 0.549 M 0.551 M 0.548 M 0.549 M a. Calculate the average molarity of the acid. Show your work. Use correct significant figures and units. b. Discuss your analysis of the accuracy and precision of this student's results if the true value was found to be 0.600 M 123 45
