Density.
The amount of salt and minerals (salinity) increases the water's density and affects the ability of an object to sink in saltwater - for example, it is nearly impossible to sink if you're swimming in the Great Salt Lake in Utah due to the high salinity of the lake. The higher the salinity content, the harder it is to sink an object.
If an object floats in water it will also float in the much denser mercury
something lighter than water
It is lighter than water

the amount of density
The object floats in the water.
Yes. A floating object displaces its own mass in water.
If the object floats it is less dense than water, if it submerges it is denser than water.
An object will float in water if it has LESS density than the water.
We both know it floats
what object will not sink or float but will stay suspended in the middle of water
It's because of the density of the object; for example wood floats in water because its density is less then the density of water, and metal sinks because its density is more then the density of the water.
