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/mol. before investigating the scene, the technician must dilute the luminol solution to a concentration of 4.00 ã 10â2 m . the diluted solution is then placed in a spray bottle for application on the desired surfaces. how many millimoles of luminol are present in 1.92 l of the diluted spray
