It increases.
the salt makes seawater denser than freshwater. more salt increases the density
The temperature of the water and the salt content of the water.
Yes. Salt water has a slightly higher density then fresh water which means its a little easier for things to float in salt water. So if it floats in fresh water it will certainly float in salt water.
Salinity refers to the concentration of salt in water, while density refers to how tightly packed the molecules of a substance are. Salinity can affect the density of water, as the more salt in water, the denser it becomes.
When salt is dissolved in water, the mass of the water increases without a significant increase in volume, increasing the density of the solution. This is because the added salt molecules displace some of the water molecules and fill the space in between them, making the solution denser.
In aspect of egg floated in salt water is no, egg didn't change it's density just salted water is more dense. In the aspect of salted egg (marinaded in salted water for a week) is yes. Diffused salt content would increase the density of the egg.
No salt has a greater density.
Salt water density really depends on a few different things. The concentration of salt and temperature are the 2 largest factors in determining the density of salt water.

The floatation of a raw egg in water is influenced by the density of the water compared to the density of the egg. When the density of the water increases (for example, by adding salt), the egg may float because it becomes less dense than the surrounding water. Conversely, if the water's density decreases, the egg may sink, as it becomes denser than the water. Thus, adjusting the water's density can determine whether the egg floats or sinks.
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
