      I didn’t know the answer to this question so I did some googling. Apparently there is roughly 35 grams of salt in every litre of sea water, and the world’s oceans contain about one sextillion (that’s 1 followed by 21 zeros) litres of water.
      So the worlds oceans contain about 35 sextillion grams of salt, that’s a billion billion kilograms of salt!

      That would cover quite a few fish and chips.
