Problem- Part A The forensic technician at a crime scene has just prepared a luminol stock solution by adding 10.0g of luminol into a total volume of 75.0 mL of H2O.
What is the molarity of the stock solution of luminol?
Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 6.00×10?2M . The diluted solution is then placed in a spray bottle for application on the desired surfaces.
As much detail as probable is really appreciated
