A sample of nitrogen gas is stored in a 557.9 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 24.1°C. What is the pressure of nitrogen in the second flask?

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.

Calculate the concentration of all species in a 0.165 m solution of h2co3.
