Density is equal to the ratio of mass to the volume.
The mathematical expression is given as:
Arrange the above expression in terms of volume, i.e.
Density of osmium is equal to =
Mass of osmium = 4.80 kg
First, convert the mass in kg to g:
1 kg = 1000 g
Therefore, mass in g = = 4800 g
Put the values,
= .
Hence, volume occupied by osmium =.
