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.
1.The forensic technician at a crime scene has just prepared a luminol stock solution by adding 18.0 g
of luminol into a total volume of 75.0 mL of H2O
What is the molarity of the stock solution of luminol? 1.36M
2.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? .120 mol
3.What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?
The gestation period for human births can be taken as normally distributed with a mean of 266 days and a standard deviation of 16 days.
If a gestation period if 276 days, what percentile among human births is this?
