A fish sample was analyzed for crude protein content using the Kjeldahl method. The following data were recorded: Moisture content 10.0% Weight of sample 2.15 g Normality of HCl used for titration 0.121 N HCl used for sample 28.5 mL HCl used for reagent blank 0.2 mL Calculate crude protein content on wet weight basis of the fish sample, assuming fish protein contains 20% nitrogen.
