Evaporating the water sodium chloride remain as a residue.
Desalination
The term is Desalination.
Dissolved salts are transported by the rivers.
Precipitation, land water runoff and the melting of icebergs do not add salts to seawater.
The average salinity of seawater is about 35 grams of dissolved salts per kilogram of seawater, or 3.5% by weight.
Sea water doesn't contain organic salts.

Desalination.
The most important is sodium chloride - NaCl.
It is dissolved salts, gases, and nutrients that are presented in seawater.

Approximately 30 -40 grams of salts per kg
