The sea water has a sodium chloride concentration of approx. 35 g/L.
Generally the concentration of salt in a water solution (at 20 0C) is very variable, from parts per million to 360,9 g/L (36,09 g/100 g).
Approximately 97.5 percent of all the water on Earth is salt water. Of the remaining 2.5 percent that is fresh, about 70 percent exists as ice.
In the world,1% is fresh water,2% ice, and 97% salt water.
About 70 percent of the Earth's surface is covered in water, and about 90 percent of that is salt water.
Sea water has arround 3.5 % of salt.

Water with a salt concentration of about 3.5% is typically found in seawater.
75% of the water, I would assume.
3.5 percent salt and 97.5 is water.
around 80 percent
