ρ=2.5⋅g⋅cm3............
Explanation:
ρ=Mass/Volume=5⋅g2⋅cm3,
and thus typically it has the units g⋅mL−1 or g⋅cm−3.
Here, mass=5⋅g, and volume=2⋅m3.
Their quotient is the density as shown. And this could be any solid material (generally solids are denser than liquids). You will have to look up tables of densities for common materials.
