The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 g of luminol to H_2O creating a solution with a total volume of 75.0 mL.
What is the molarity of the stock solution of luminol?
1.28M
Before investigating the scene, the technician must dilute the luminol solution to a concentration of 5.00×10^-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?
0.100 mol luminol
What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?
