After big bang surface and the core of the earth were highly temperatured passes of time there created many large holes on the surface of the earth.

At the meantime, there was heavy rainfall about 200 cores of simultaneously the water flowed from the surface of the earth and finally dropped into that holes. During the flowing time, various kinds of salt mixed into the water and thus the water became salty. And if the vapour 1-liter water then you can get about 3.5 g salt. And total water of the world only 1% water is drinkable.

Salt means that substance formed by acid and base in a decided ratio.

@Maheswar Majhi.

Salinity means presence of avarege quantity of Nacl in a fixed cubic bowl.

Salinity means. How much salt dissolved in it. Below 5ppt called fresh (mitha) and 5 to 35 ppt sea ka hota h. Please convert it in%.

What is meant by silent water?

The average salinity of sea water is 35 g/L (grams per thousand) about 35 parts per thousand.

In the open ocean away from land the salt content (or salinity) of the seawater tends to range between 30 and 35 ppt (parts per thousand). This is equivalent to 3.0 to 3.5 % (or parts per hundred).

Salinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt or).

The average ocean salinity is 35 ppt and the average river water salinity is 0.5 ppt or less. This means that in every kilogram (1000 grams) of seawater, 35 grams are salt.

I can't understand what is mean by 3.5 salinity of sea water?

3.5% means what out of 100%?
