The forensic technician at a crime scene has just prepared a luminol stock solution by adding 20.0 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) HÀ ? molarity of luminol solution = Value Units Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 2.00x10-2 M . The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray? Express your answer with the appropriate units.

Please answer question 1 Part A and B

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 Part A The forensic technician at a crime scene has just prepared a luminol stock solution by adding 20.0 g of luminol into a total volume of 75.0 mL of H2 O. diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing 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 = Value Units Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 2.00x10-2 M .
