Magnesium is a valuable metal used in alloys, in batteries, and in synthesis. It is obtained mostly from seawater, which contains about 1.3 g of Magnesium for every kilogram of seawater. Calculate the volume of seawater (in Liters) needed to extract 8 x 10 4 tons of Magnesium which is roughly the annual production in United States. (Density of seawater is 1.03 g/mL)
