urses/ 2951 2. A linear standard curve of KMnO4 is prepared from a set of standard solutions by plotting absorbance (y) vs. concentration (x). Use Logger Pro (as described in the Data Analysis for this experiment), or Google Sheets/Excel, to plot this standard curve using the data in Table 1. Help with spreadsheets [PDF] Table 1: Data for the standard curve of KMnO4 Absorbance Concentration (M) 0.372 6.00 x 10-4 0.298 0.223 0.149 0.0744 After plotting the standard curve, enter its slope below (not the equation of the line). Report your answer to 3 significant figures. If your answer ends in one or more zeros, use scientific notation. Slope = 4.80 x 10-4 3.60 x 10-4 2.40 x 10-4 1.20 x 10-4 M-1 M 3. Suppose that an unknown sample is analyzed spectrophotometrically at the same wavelength that was used for the standard curve and the absorbance was found to be 0.186. Use the standard curve to find the concentration of the unknown. Hint:

Given the diameter of the asteroid to be (8.50x10^0) km and the density of the asteroid to be (2.1100x10^0) g/cm, calculate the total mass of the asteroid. Remember to round your answer to the correct number of significant figures Note: The answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm^2. Note: Your answer is assumed to be reduced to the highest power possible.

Tim is interested in analyzing for Pyraclostrobin (pesticide) in strawberries using QuECHers method for extraction and clean up before analysis with HPLC-uv. The concentration of the Pyraclostrobin in the fruits that he sampled is thought to be between 1-10 ng pesticide per g fruit fresh weight. The HPLC-uv instrument he is using has a LoQ of 5 ppb for Pyraclostrobin. Tim is starting out with 500 mg of the sliced fruit
