The absorbance of potassium permanganate was analyzed at 530nm and a 1.0cm cuvette was used. Five standard concentrations were prepared, and the absorbance of the standards and sample is shown in the table. 1. Determine the equation of the line. 2. What is the molar absorptivity of the absorbing species? 3. Calculate the linearity of the calibration curve. 4. What is the concentration of the analyte in the sample? 5. What is the calibration method used in the
