Instructor's OK signature: AU 0.35SAU 29 Beneath the Things We See POST-LAB QUESTIONS 1. Your data table on the spreadsheet must have appropriate column titles. Fully label your calibration graph on MS Excel. Include your graph with this report along with the data table 2. Given that the cuvette used in this experiment has a path length of 1.0 cm, calculate the molar absorptivity (e) of CV solution using the Beer-Lambert law, A=cbc, at any absorbance (average) along with its corresponding standard molarity. Comment on how your calculated answer compares to the slope (cb) of the calibration graph (in AU/mol.L) when y-intercept is zero. The molor aboobtion at any absorbana considering y interapt is on will be given as such - AEbc let, A= 3. Use the equation of the calibration graph to determine the molarity (M) in the unknown CV solution Show your work. 4. If the unknown CV solution you analyzed was made by diluting a 0.50-ml sample of the original to 10.00 ml, calculate the molarity of the original CV solution -000- END OF LAB REPORT
