From Wikipedia, the free encyclopediaSea water in the Strait of Malacca
Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram (2.2lb), or every litre, of seawater has approximately 35 grams (1.2 oz) of dissolved salts (mostly, but not entirely, the ions of sodium chloride: Na+, Cl−). The average density of seawater at the ocean surface is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4 °C (39 °F)) because of the salts' added mass. Thefreezing point of sea water decreases with increasing salinity and is about −2 °C (28.4 °F) at 35 g/l.[1]

Because of evaporation, the infusion of freshwater is necessary to maintain the existing salinity percentage.
The majority of the Earth's water is saltwater found in oceans. Only a small percentage, about 2.5%, is freshwater. However, much of this freshwater is frozen in ice caps and glaciers, or stored underground in aquifers, making only a small percentage of freshwater readily available for human use.
usually freshwater.......
3% is freshwater
No Oceans are not Freshwater, they are salt water
Ocean water has salt in it, Freshwater does not.
in the ocean
It is 787.975 in seawater and freshwater's is 211.
they lay egg in the ocean
In an ocean.
The average salt concentration in the Pacific Ocean is around 3.5%, which is equivalent to 35 grams of salt per liter of seawater. This percentage can vary slightly in different regions of the ocean due to factors like evaporation rates and freshwater input from rivers.
