I suspect by gL you mean g/L. Borrowing from another Q/A here:
http://wiki.answers.com/Q/How_many_grams_of_salt_are_in_one_cup We'll assume 1 cup sea salt is 400 grams. 1 gallon = 3.7854L, so 1cup salt in 1 gal water = 400/3.7854 = 106 g/L You're asking for RSD in a way that doesn't make sense - maybe rephrase it or describe the information you're looking for.
Chlorine is usually produced by the electrolysis of seawater.
Relative salinity is the most important factor in seawater density.
Bromine is found naturally in the earth's crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools.
The density of seawater increases if salinity increases.
97% seawater, other 3% is freshwater.
Concentration range of seawater acidity
The cup of seawater has more salt, but the concentration, that is, the amount that it is diluted, is exactly the same.

Relative salinity is the most important factor in seawater density.
Seawater is a mixture of various salts and water. Only six elements and compounds comprise about 99% of sea salts: chlorine, sodium, sulfur, magnesium, calcium and potassium. The relative abundance of the major salts in seawater is constant regardless of the ocean. Only the amount of water in the mixture varies because of differences between ocean basins because of regional differences in freshwater loss (evaporation) and gain (runoff and precipitation). The chlorine ion makes up 55% of the salt in seawater.
precipitate out the solution
hypertonic and hypotonic are relative terms. A solution that is hypertonic to tap H2O could be hypotonic to seawater. In using these terms, you must provide a comparison, as in 'the solution is hypertonic to the cells cytoplasm'.
Chlorine occurs commonly both in the Earth's crust and in seawater
