Crime scene investigators keep a wide variety of compounds on hand to help with identifying unknown substances they find in the course of their duties. One such investigator, while reorganizing their shelves, has mixed up several small vials and is unsure about the identity of a certain powder. Elemental analysis of the compound reveals that it is 63.57% carbon, 6.000% hydrogen, 9.267% nitrogen, 21.17% oxygen by mass. Which of the following compounds could the powder be?

a.) C11H15NO2 = 3,4-methylenedioxymethamphetamine (MDMA), illicit drug

b.) C3H6NO3 = hexamethylene triperoxide diamine (HMTD), commonly used explosive

c.) C21H23NO5 = heroin, illicit drug

d.) C8H9NO2 = acetaminophen, analgesic

e.) C7H5N3O6 = 2,4,6-trinitrotoluene (TNT), common used explosive

f.) C17H19NO3 = morphine, analgesic

g.)C10H15N = methamphetamine, stimulant

h.) C4H5N2O = caffeine, stimulant
