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