How many coulombs of electrical charge would be required

Some years ago a unique proposal was made to raise the Titanic. The plan involved placing pontoons within the ship using a surface-controlled submarine-type vessel. The pontoons would contain cathodes and would be filled with hydrogen gas formed by the electrolysis of water. It has been estimated that it would require about 7 X 108mol of H2 to provide the buoyancy to lift the ship (J. Chem. Educ., 1973, Vol. 50, 61).

(a) How many coulombs of electrical charge would be required?

(b)What is the minimum voltage required to generate H2 and O2 if the pressure on the gases at the depth of the wreckage (2 mi) is 300 atm?

(d)What is the minimum cost of the electrical energy required to generate the necessary H2 if the electricity costs 85 cents per kilowatt-hour to generate at the site?
