If 120 ml of water is displaced means, volume of stone is 120 ml.
 
weight of stone in water = volume×(ρs - ρw)g = 120×(ρs - ρw)g  gram.
 
where ρs is density of stone, ρw  is density of water.

mass of the stone and density of stone will remain same everywhere, they will not change when stone is inside water.
