Earth’s oceans have an average depth of 3800 m, a total surface area of 3.63x10⁸ km², and an average concentration of dissolved gold of 5.8x10⁻⁹ g/L.
(a) How many grams of gold are in the oceans?

The quantity of gold in the ocean is 8x10^12 g

A=3.63x10^8  km^2 = 3.63x10^14   m^2

L = 3800m

We calculate the volume of the ocean this is achieved by multiplying the area by the depth.

V=3.63x10^14 x 3800 = 1.3797x10^18m^3 = 1.3797x10^21L

Now we multiply the volume in liters by the concentration of gold in the ocean per liter,

grams of gold=1.3797x10^21 x 5.8x10^-9 = 8x10^12 g
