greater density tends to less buoyancy
The effect of buoyancy is to reduce the apparent weight of the object when it's introduced into a fluid. Depending on the density of the object compared to the density of the fluid, the object's apparent weight could be reduced to zero (beach ball floating in the pool), or even to a negative value (helium party balloon heading for the sky).
Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.
They have to be the same.
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
Salinity increase the water density. Therefore the more salt you add to water, the greater its density becomes.The higher the density of the fluid, the greater the mass of the object that can float in it.Hence rise in salinity of a liquid will increase the buoyancy.

A body has positive buoyancy when its density is lower than the density of the fluid the body is in.

Yea
Buoyancy is the ability to float, so if the density is high, it'll hold up something. (see? FLOATING. BUOYANCY.)
An object with greater density than the liquid it is placed will tend to sink
It is average density.
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.
A life jacket is also known as a floatation or buoyancy aid - it acts to increase your buoyancy. So what do we mean by this? Well, buoyancy can be described simply as how easily an object will float in a fluid (or gas), where the more buoyant the object the better it will float. Buoyancy is related to the density of an object which is in turn related to the amount of mass a given object has relative to it's volume. As the density of an object gets larger compared to the density of the fluid it is floating in, its buoyancy will decrease and it will become less able to float. As the density of the object becomes larger than the density of the fluid it is floating in, it will sink. Now that we understand buoyancy, we can explain how a life jacket works. A life jacket is mainly filled with gas which has a very low mass. As such when worn by a person, it acts to significantly increase their volume for only a very small increase in their mass. This means that they have a lower density than normal which increases their buoyancy and helps them to float.
