Minerals like halite and gypsum often form from evaporation. This occurs when 1. when water evaporates, some of it turns into minerals if it bumps into rocks on the way up.

2. mineral molecules dissolved in water evaporate with the water, forming tiny mineral crystals in the clouds that fall back to earth when it rains.

3. mineral molecules dissolved in water are left behind when the water evaporates, forming solid crystals.

4. mineral molecules dissolved in water turn solid when the water becomes very hot.

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.
