Seawater contains 3.00 mg of uranium per cubic meter.
Given:
The average ocean depth,
Water covers two-thirds of the Earth's surface
Then, the estimated amount of uranium dissolved in the ocean is .
We know, that the mass per unit volume of Uranium is.
Also, the world's energy requirement is .
The radius of the earth is .
Calculating the amount of Uranium under the seawater is given by the expression:
Substituting all the values in the expression, we get
.
Thus, the amount of Uranium dissolved in the ocean is
