in enamel from extracted wisdom teeth donated by ancient
mummies. They decided to measure the concentration of Sr in
the teeth by atomic absorption spectroscopy. Solutions were
prepared with a constant total volume of 10.0 ml containing .750 mg
of dissolved tooth enamel plus variable concentrations of added
Sr. Below you will see a graph of collected data.
