It is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating.
Dead sea in Israel has salinity of 45 parts per thousand. Swimmers can float in it because the increased salt content make it dense.

Introduction:
The Dead Sea is a saltwater lake bordered by Jordan to the east and Israel and Palestine to the west. The Dead Sea is the deepest hypersaline lake in the world and is known for its high salt content.
Salinity of Dead Sea:
The salinity of the Dead Sea is 45 parts per thousand. This means that there are 45 grams of salt for every liter of water in the Dead Sea. The high salt content of the Dead Sea is due to the fact that it has no outlet and is surrounded by arid desert regions that receive very little rainfall.
Comparison with other water bodies:
The salinity of the Dead Sea is more than 8 times higher than that of the ocean. The average salinity of the ocean is around 3.5%, whereas the salinity of the Dead Sea is around 34%. The Dead Sea is also much saltier than other saltwater lakes such as the Great Salt Lake in Utah, which has a salinity of around 5-27%.
Effects of high salinity:
The high salt content of the Dead Sea has several effects. Firstly, it makes the water very buoyant, which means that it is easy to float in the Dead Sea. Secondly, the high salt content makes the water very dense and heavy, which means that it is difficult to swim in the Dead Sea. Finally, the high salt content means that the Dead Sea has a unique ecosystem, with only a few species of bacteria and algae able to survive in its waters.
Conclusion:
In conclusion, the salinity of the Dead Sea is 45 parts per thousand. The high salt content of the Dead Sea has several effects, including making the water buoyant and dense, and creating a unique ecosystem.
