Question
Chapter 10.5, Problem 10.20P
Interpretation Introduction
Interpretation:
The fraction of thallium-201 present in an individual after nine days should be determined at given conditions.
Concept introduction:
The half-life of radioactive materials is based on the disintegration of one-half of the atoms of the radioactive material. This estimation is used by scientists to determine the age of organic materials. Mostly, it is carbon-14 that is used to estimate.

and Pro and once with a cis peptide bond between Tyr and Pro.
b) The electrospray ionization mass spectrum (ESI-MS) of the tripeptide you
designed in part (a) shows peaks indicative of mono-protonation and di-

- Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample.
