The density of the object is 0.032 g/cm^3.
<h3>What is density?</h3>
The term density means the ratio of the mass to the volume of an object. Now we know that when an object is dense that it would sink to the bottom of a fluid.
Now given that;
Mass = 0.8 g
volume= 25 cm^3
Density = mass/volume
Density = 0.8 g / 25 cm^3
= 0.032 g/cm^3
