The chemical 5-amino-2,3-dihydro-1,4-phthalazine dione, 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/molthe forensic technician at a crime scene has just prepared a luminol stock solution by adding 14.0g of luminol into a total volume of 75.0 ml of h2o. what is the molarity of the stock solution of luminol? before investigating the scene, the technician must dilute the luminol solution to a concentration of 3.00
