Textbook Question
Chapter 3, Problem 3.68PAE
3.68 Magnesium is lighter than other structural metals, so it
is increasingly important in the design of more efficient
vehicles. Mg2+ ions are present in seawater, and the
metal is often prepared by "harvesting" these ions and
converting them to Mg metal. The average magnesium
content of the oceans is about 1270 g Mg2+ per ton of
seawater, and the density of seawater is about 1.03 g/mL.
What is the molarity of Mg2+ ions in seawater? The
design for a concept car calls for 103 kg of magnesium
per vehicle. How many gallons of seawater would be
required to supply enough magnesium to build one of
these ears?

- Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4- 1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
