What is the maximum concentration of salt in water?

Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. 
The saturation level is dependent on the temperature of the water. At 20 °C one milliliter of water can dissolve 
about 0.357 grams of salt; a concentration of 26.3%.
