The chemical 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. Luminol has a molecular weight of 177 g/mol. The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 g of luminol into a total volume of 75.0 mL of H₂O. What is the molarity of the stock solution of luminol? Express your answer with the appropriate units. ► View Available Hint(s) molarity of luminol solution = 1.28 M Submit Correct Part B Previous Answers Before investigating the scene, the technician must dilute the luminol solution to a concentration of 4.00 × 10-2 M.
