The surface ocean contains about 2.6x1016 liters of water with a carbonate ion content of about 2x10-4 mol/L. The deep ocean contains about 1.4x1021 L of water with a carbonate ion content of roughly 9x10-5 mol/L. If each mole of carbonate reacts with 1 mol of CO2 according to the reaction
CO2 + CO32- + H2O -> 2HCO3-
1)what percentage of the fossil-fuel reservoir, 4200 Gt(C), can be neutralized by the surface ocean?
