Assume that 0.015 % of the hydrogen atoms in seawater (H2O) are deuterium. The atomic mass number of oxygen is 16.

Assume that 0.015 % of the hydrogen atoms in seawater (H2O) are deuterium. The atomic mass number ofoxygen is 16. About how many kilograms of seawater would be needed per year to provide the hydrogenfuel for fusion reactors to meet the energy needs of the United States?
