Please answer question 1 Part A and B The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is usedby forensic scientists in analyzing crime scenes forthe presence of washed-away blood. Luminol is sosensitive that it can detect blood that has beenPart AThe forensic technician at a crime scene has just prepared a luminol stock solution by adding 20.0 g of luminol into atotal volume of 75.0 mL of H2 O.diluted 10,000 times. A basic solution of luminol isoften sprayed onto surfaces that are suspected ofcontaining minute amounts of blood.What is the molarity of the stock solution of luminol?Express your answer with the appropriate units.Luminol has a molecular weight of 177 g/mol.• View Available Hint(s)µA?molarity of luminol solution =ValueUnitsPart BBefore investigating the scene, the technician must dilute the luminol solution to a concentration of 2.00x10-2 M .
