Answer:
30 cm³.
Step-by-step explanation:
The following data were obtained from the question:
Density (D) = 2.7 g/cm³
Mass (m) = 81 g
Volume (V) =...?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It can be represented mathematically as:
Density (D) = mass (m) /volume (V)
D = m/V
With the above formula, we can obtain the space (volume) occupied by the aluminium as follow:
Density (D) = 2.7 g/cm³
Mass (m) = 81 g
Volume (V) =...?
D = m/V
2.7 = 81/V
Cross multiply
2.7 × V = 81
Divide both side by 2.7
V = 81/2.7
V = 30 cm³
Therefore, the space occupied by the aluminium is 30 cm³.
