An object that is completely or partially submerged in a liquid will be acted on by an upward buoyant force that is equal to the mass of the displaced liquid.
Explanation:
This principle basically gives meaning to the buoyant force. If the object placed in the liquid can displace amount of liquid equal to its own mass, then its weight will be balanced by the buoyant force, and it will float precisely at the point where this balance occurs.
If the object is completely submerged before the buoyant force can equal its weight, then its apparent weight will be equal to its true weight minus the amount of the buoyant force (the weight of the displaced liquid).
Eureka!
