Constants | Periodic Table
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.
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.
