The German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from
seawater.
You may want to reference (Page) Section 2.1 while completing this problem.
Part A
Given that (1) the amount of the reparations was $28.8 billion dollars, (2) the value of gold at the time was about $21.25 per troy ounce (1
troy ounce = 31.103 g), and (3) gold occurs in seawater to the extent of 4.67 x 1017 atoms per ton of seawater (1 ton = 2000 lb), how
many cubic kilometers of seawater would have had to be processed to obtain the required amount of gold? Assume that the density of
seawater is 1.03 g/cm³. (Haber's scheme proved to be commercially infeasible, and the reparations were never fully paid.)
