What the relationship between buoyancy and density

Buoyant force is directly proportional to the density of the fluid in which an object is immersed.

Buoyancy is the tendency to rise or float in a fluid. The upward force exerted on objects submerged in fluids is called the buoyant force.

The formula for buoyant force is
F=ρVg=mg

where
ρ
is the density,
V
is the volume, and
m
is the mass of the displaced fluid.
g
is the acceleration due to gravity (9.81 m·s⁻²).

So the denser the fluid is, the greater the buoyancy and the buoyant force.
