The density of water is 1 g\/cm\u00b3. Since 0.8 g\/cm\u00b3 < 1 g\/cm\u00b3, the packet will float in water. The density of liquid B is 1.5 g\/cm\u00b3.

The buoyant force is also equal to the weight of the fluid displaced by the object. If the object sinks, the buoyant force is less than the weight of the object. The proportion of the object submerged when floating is equal to the ratio of the object&#8217;s density to the fluid&#8217;s density.
