Aluminum has a density of 2.70 g/cm3. if you have a volume of 275 cm3, what is the mass in kilograms

Density is defined as the ratio of mass to the volume.

The mathematical expression is given as:

where, d = density

m = mass and v= volume

Plug in the value of density i.e. and volume i.e.  in above formula;

Now from conversion factors, 1 kg = 1000 g

Thus, mass of aluminium in kg  =

=

Hence, mass of aluminium in kg =
