The forensic technician at a crime scene has just prepared a luminol stock solution by adding 10.0 g of luminol into a total volume of 75.0 mL of H2O.

a ) What is the molarity of the stock solution of luminal? molarity of luminol solution = 0.753 M

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? moles of luminol = 8.00×10?2 mol

c) What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?

PLEASE HELP WITH C

The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. Luminol has a molecular weight of 177 g/mol.

(Legal reasoning): Suppose a crime has been committed. Blood is found at the scene for which there is no innocent explanation. It is of a type which is present in 1% of the population. a. The prosecutor claims: “There is a 1% chance that the defendant would have the crime blood type if he were innocent. Thus there is a 99% chance that he is guilty”. This is known as the prosecutor’s fallacy. What is wrong with this argument? b....
