Potassium chromate, KCrO4, is a bright yellow solution that can be analyzed using UV/VIS Spectroscopy. A set of standards is run and the best fit line for the calibration curve is found to be A=0.479 (ppm) + 0.013 A 23.15mL aliquot of an unknown sample containing K2CrO4 was diluted to a final volume of 186.01mL. Analysis of the sample at a wavelength of? in a 1.00cm cuvette was found to have a %T = 23.47. Calculate the concentration of KCrO4 (ppm) in the unknown sample. Give your answer to 2 places after the decimal. Potassium chromate, KCrO4, is a bright yellow solution that can be analyzed using UV/VIS Spectroscopy.
