Concentrations of dissolved solids in water are often reported in parts per million (ppm) or parts per billion (ppb). One part per billion of a solute is equivalent to 1 ug (microgram) of that solute dissolved in 1 litre of water (i.e., 1 ppb = 1 ug/L). The toxic water crisis in Flint, Michigan in 2015 yielded test results of up to 1051 ppb of lead dissolved in tapwater. (The maximum allowable concentration set by Health Canada is 5 ppb)....

Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...

I need help with this questions please!
16. Tooth enamel consists mainly of the mineral calcium hydroxyapatite, Cao(PO).COH). elements in teeth of archeological specimens provide anthropologists with clues about diet and diseases of ancient people. Students at Hamline University measured the trace element strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. Solutions were prepared with a constant total volume of 10.0 mL containing 0.750 mg dissolved tooth enamel plus variable concentrations of added Sr. X]i Is If...
