if the density of an object is less than that of the liquid in which it is kept, then the object will float. that is when the buoyant force is more than gravitational force.
but if the density of the object is more than that of the liquid in which it is kept, then the object will float. that is buoyant force is less than gravitational force.
hope it helped ☺

Well, the answer is Density.
You see, if the object has a higher density than that of the liquid, it will sink (that's depressing, quite literally). If the object has less density than that of the liquid, Voila! It will float!
What is Density? What does it have to do with this?
For starters,
∴ If the Volume of one object, say D1, is greater than another object of equal mass, say D2, then the Density of the D1 is less than that of D2.
Similarly, if D1 and D2 have equal volume but D1 has more mass than D2, then D1 have a higher volume than D2.
Now if,
If the density is more, that means the mass/ per volume is more. Since mass is more, therefore the downward force (i.e. Gravitational force) is more.
Well, if the object has more density than that of the fluid, it applies a greater gravitational force on the fluid, hence the buoyant force by the liquid is no match for it (not very "uplifting'is it?). If the density of the object is less than that of the fluid, the gravitational force is pretty useless in front of the buoyant force (quite ''uplifting'' for a change). Hence, it all depends on the density in the end.
