Part B : Before investigating the scene, the technician must dilute the luminol solution to a concentration of 4.00×10−2 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?
: = .×^-

PART C :What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?
I only need help with part C. Please , Its due at 11.59.
