about 70 percent of water covers the world
Percentages of salt found in seawater is known as salinity. The salinity in water can be measured using a refractometer or a salinity sensor.
A sample of known mass is diluted to a particular volume.
100 % is defined as 1 gram of solute per milliliter of solvent, so (for example) 5 g diluted to 100 mL gives a 5 % solution.
1. By densimetry (see also the the link below for a table)
2. Determining the concentration of sodium or chloride ions in the water solution
Percentage of water = (Mass of n water molecules in the hydrate x 100)/molar mass of the hydrate
Percentage of water = (Mass of n water molecules in the hydrate x 100)/molar mass of the hydrate

There are a few things that is good about IV solution and salt. The body needs salt and water. Not only that but if someone were to be given plain water, their cells would take in too much water and get damaged or burst and that will damage the body. The salt in the IV solution should be about the same percentage of water and salt as healthy cell.
there is salt in salt water and little salt in fresh water
there is no salt water in the candy "salt water taffy." it is just the name/brand.
The solvent is water, the solute is salt; solvent and solute form a solution.
The percentage of salt in the sea is 3.5%
98% of all water
3.5 percent salt and 97.5 is water.

97% of the worlds water is Salt water. 71% of the world is Covered by Saltwater.
The greatest percentage of salt is extracted from mines. You get sea water and put it in a evaporating dish. Then evaporate the water and then there is salt left.

Around 3% or slightly more.
About 70 percent of the Earth's surface is covered in water, and about 90 percent of that is salt water.
