hemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. Part A The forensic technician at a crime scene has just prepared a luminol stock solution by adding 12.0 g of luminol into a total volume of 75.0 mL of H,O. Luminol has a molecular weight of 177 g/mol. What is the molarity of the stock solution of luminol? Express your answer with the appropriate units. > View Available Hint(s) HẢ ? molarity of luminol solution = Value Units Submit Previous Answers Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 5.00x10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00L of the diluted spray?
