Question:

Magnesium (Mg) is a valuable metal used in alloys, in batteries, and in the manufacture of chemicals. It is obtained mostly from seawater, which contains about 1.3 g of Mg for every kilogram of seawater. Referring to Problem 1.71, calculate the volume of seawater (in liters) needed to extract 8.0 x 104 tons of Mg, which is roughly the annual production in the United States.
