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

Hydrocarbons in the cab of an automobile were measured during trips on the New Jersey Turnpike and trips through the Lincoln Tunnel connecting New York and New Jersey. The total concentrations ( ± standard deviation) of m- and p-xylene wereTurnpike: 31.4 ± 27.0 μg/m3 (32 measurements)Tunnel: 54.9 ± 29.8 μg/m3 (32 measurements)Do these results different at the 95% confidence level?
You have a solution with a concentration of 0.80 mM, and you put it in a cuvette with a 1.0cm pathlength. You read an absorbance of 0.400. What is the extinction coefficient of your analyte? Question 4 options: 0.50 mmole/L/cm 0.50 mmol/L (cm)-1 0.50 L/mmole/cm 0.50 mM cm
After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40, a student found that her best fit linear line for FD&C Red 40 was y = 2,962x + 0.005. Her Kool-Aid sample had an absorbance of 0.685. If 0.543 grams of Kool-Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her 8-fl oz cup?
