Tooth enamel consists mainly of the mineral calcium hydroxyapatite, Can(PO)(OH). Trace elements in teeth of archeological specimens provide anthropologists with clues about diet and disease of ancient people. Students at Hamline University measured the trace element strontium in cnamel from extract wisdom teeth by atomic absorption spectroscopy. Solutions were prepared with a constant total volume of 10.0mL. containing 0.750mg dissolved tooth enamel plus variable concentration of added Sr. \table[[Added Sr (ng/mL- ppb), Signal (arbitrary units)], [0, 28.0], [2.50, 34.3], [5.00, 42.8], [7.50, 51.5], [10.00, 58.6]] a) Prepare a graph to find the concentration of Sr in the 10mL sample solution in part per billion = n m L.
