A 4.277-g sample of Al2(SO4)3 was dissolved in distilled water to make a total
volume of 250.0 mL of solution A. Then an aliquot of 25.00 mL of solution A
was diluted 10 times with distilled water to give solution B. Determine the
molar concentration of the sulfate ions in solution B.

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
