Before investigating the scene, the technician must dilute the luminol solution to a concentration of 5.00x10-2 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 2.00L of the diluted spray?
Exprêss your answer with the appropriate units.
