Which statement best compares the density among the three states of matter?
solids have the least density among the three, gases have the highest, and liquids are slightly less dense than gases but much denser than solids.
liquids have the highest density among the three, gases have the lowest, and solids are slightly less dense than liquids but denser than gases.
solids have the highest density among the three, gases have the lowest, and liquids are slightly less dense than solids but much denser than gases.

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.
