In the following table, enter the values called for from your experimental results. Then calculate the percent error for the differences between the values you obtained for the solution of unknown concentration in Part A, and the results you obtained in Part B and Part C. The equation for percent error is: % difference = ((theoretical value - actual value) x 100%) / theoretical value. A percent difference can be positive or negative. Treat the concentration you measured in Part A as the theoretical value, the one you're trying to match. TABLE A. Error analysis for copper(II) sulfate solution preparations. Absorbance
