If 8.500 g of sodium nitrate and 7.500 g of potassium chloride are dissolved in 25.0 mL of water and heated to 80°C no solid Watermain. Using these amounts of potassium chloride and sodium nitrate, calculate the theoretical number of grams of sodium chloride and potassium nitrate that could be formed.

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.
