Buoyant force = volume of liquid expelled x density of liquid x acceleration due to gravity
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.
As buoyant force decreases then the body starts sinking down.
the 'buoyant' force
well it's easy..:D we consider a cylindrical portion of a liquid and find that on an average the object(water itself) remains stationary. This gives us an idea that the upward force(buoyant force) equals the gravitational force. Therefore the buoyant force in this case is the "mg" itself but in fluids we talk in terms of the volume and density so it is V(rho)g. Plus this buoyant force in any case is independent of the object coz' it is fundamentally rooted to the Brownian motion and striking of the particles on the object which leads to the upward force. So it only depends on the volume of the object. And the buoyant force is defined as Volume *density of liquid*g.

Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
A buoyant force equals the weight of the fluid being displaced
Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.
The buoyant force depends on the volume of liquid displaced and the density of the liquid.

buoyant force = density of the liquid*Volume*gravity. so the buoyant force is directly proportional to the density of a liquid.
The buoyant force is a contact force, exerted by contact with a liquid that displaces the liquid within a gravity field. No contact, no force.
Buoyant force reduces the weight of the body
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
