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

The mathematical expression is given as:

$d =\frac{m}{v}$

where, d = density

m = mass and v= volume

Plug in the value of density i.e. $2.70 g/cm^{3}$ and volume i.e. $275 cm^{3}$ in above formula;

$2.70 g/cm^{3} =\frac{m}{275 cm^{3}}$

$2.70 g/cm^{3}\times 275 cm^{3} = m$

m = 742.5 g

Now from conversion factors, 1 kg = 1000 g

Thus, mass of aluminium in kg = $\frac{742.5}{1000}$

= 0.7425 kg

Hence, mass of aluminium in kg = 0.7425 kg
