An oscillation is brought about by a small displacement of weight submerged a liquid medium. The liquid is damping the oscillation. How does mass of the weight affect the extent of damping?
Is inertia in play? or upthrust? Or it is correct to say either.

The oscillations will be damped because of the viscous force of liquid.The viscous force force of a liquid is independent of thr mass of the object which is submerged in the liquid.This force is proportional to the area in contact with object and the velocity gradient.

I disagree.  True the damping force depends on the area but the acceleration depends on the mass i.e. the volume.  Thus a denser mass having the same area as a less dense one will be harder to slow down.
  It can be shown that the time constant of the decay of the oscillation  is
$$2M/R$$
Where M is the mass and R is the a measure of the retarding force when the force is proportional to the velocity of the mass.  

That is when the retarding force is 

F=-R*v
