8. (12 pts) Elemental mass percent compositioncan can be used to determine the identiy of an unknown substance. a The hallucinogenic drug LSD has the molecular formula C20HasN30. If the molecular mass of LSD is 323.43 g/mol, what is its mass percent 0? b. Campus security finds an unknown sample that they suspect is LSD. The unknown sample contains 74.07% 7.95% H, and 9.99% N. by mass. Keeping in mind the law of conservation of mass, determine the mass percent...
