I don't learn chemistry yet but I see where you are right now... I think this will change in the near future because we will only have the ocean water to survive... So we purify the water... Because this will almost be all we have, we'll have no choice BUT to make money on this.... Sorry if it's wrong I don't learn chemistry yet
Atomic no = no of electrons present in atom
and atomic mass = no of protons + no of neutrons
