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

Which one is the incorrect statement regarding mass spectrum? Question 25 options: In case of alcohols, M-18 peak is produced due to the loss of neutral H2O molecule (Dehydration) The relative heights of (M)+• peak and (M+1)+• peak is used to calculate the number of carbon atoms The structure likely contains a bromine atom if the (M+2)+• peak and (M)+• are almost similar in heights The molecular ion peak (M)+• always represent the base peak The structure likely contains a chlorine atom if the (M+2)+• peak is approximately one-third as tall as (M)+•

In the interference experiment preformed, sodium ascorbate powder was added to water to prepare the stock concentration of the interfering substance. On the package label, the manufacturer states that every 1 gram (1,000mg) of sodium ascorbate powder contains 120mg of sodium and 880mg of ascorbate (vitamin C). How much sodium ascorbate must be weighed out (in milligrams) and added to 100 mL of water in order to have a final stock concentration of pure ascorbate equal to 250 mg/dL?
