Before investigating the scene, the technician must dilute the luminol solution to a concentration of 6.00×10−2 M

Question

. 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?

Answer 1

To find the number of moles of luminol present in 2.00 L of a 6.00×10^-2 M solution, we can use the formula:

moles = Molarity x Volume

moles = 6.00×10^-2 mol/L x 2.00 L
moles = 0.12 mol

Therefore, there are 0.12 moles of luminol present in 2.00 L of the diluted spray.
