QUESTION 1 To determine the concentration of iron in an unknown sample, a chemist analyzed the sample five times, and obtained the following results: 386.79 ppm, 100.705 ppm, 198.506 ppm, 317.283 ppm, and 141.159 ppm. If the accepted value for the concentration of iron in this sample is 144.07 ppm Fe, determine the percent error for the set of analyses. (Accepted values have two decimal places; however the results have three decimals places.)
