Question

Results and Data Analvsis 1. Attach to the last page of this report the following: a- spectrum of riboflavin. b. Standard curve for riboflavin. 2. The peaks are located at 440 4 with absorbance values of 3. Data for standard curve Table 2: Standard Curve for Riboflavin Tube 53.1 M Riboflavin (mL) 0.00 2.00 4.00 6.00 8.00 Distilled water Concentration Absorbance at (mL) 10.00 8.00 6.00 4.00 2.00 0.00 peak wavelength 2 lob lol 3 10.00 6 Data derived from the standard curve Data from computer-generated graph 4. Experimental value ofthe extinction coefficient Theoretical value of the extinction coefficient Percent error 5. Concentration of riboflavin sample (mg/mL) | Code number of your unknown sample Experimental value True value Percent error 12.2 x 10 M cm 93

Explanation / Answer

First sustract experimental value with true value. you get the difference of that both.

sencond, the obtained difference value divided with true value and multiplied with 100 you will get percentage error.
