Question 1 In an experiment to determine the riboflavin by fluorescence spectrometry, a series of riboflavin standards was analyzed and gave a calibration with a slope of 1000 ppm 1 and a y intercept of 25. If a sample gave a fluorescence reading of 750, what is the riboflavin concentration (in ppm) of the sample? O A. 7.50 О в. 0.0750 OC.0.725 O D. 0.775
