density=mass/volume
1mL=1cm^3, so 30.0 mL=30.0 cm^3
then you divided the volume 30.0 by the mass 81.0 grams is euqal to 81.0 grams/30.0 cm^3=2.7 g/cm^3(that's the units)

What is the mass of a chunk of aluminum?
The mass and volume of aluminum are related by density: mass = volume x density and density depends upon temperature and pressure. Aluminum has a density of 2.70 grams per cubic centimeter in its solid state. In its liquid state, Aluminum has a density of 2.375 grams per cubic centimeter.
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
