On average, seawater in the world's oceans has a salinity of ~3.5%. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
<h3>What is salinity ?</h3>
The saltiness or quantity of dissolved salt in a body of water is known as salinity (see also soil salinity). The standard units of measurement are grams of salt per liter (g/L) or grams per kilogram (g/kg; the latter is dimensionless and equal to ).
Salinity is a thermodynamic state variable that, along with temperature and pressure, controls physical properties like the density and heat capacity of the water. Salinity plays a significant role in determining many aspects of the chemistry of natural waters and of biological processes within them.
An isohaline, or isohale sometimes, is a contour line with a constant salinity.
The concept of salinity in rivers, lakes, and the ocean is straightforward, but it is difficult to define and measure properly on a scientific level.

The best example I
can give that is observable but does not contain matter is:
sunlight or simply light
Light does not contain matter because it is a beam of energy
or to be specific made up of packet of photons.
