Aluminum has a density of 2.7 g/cm3, how much space in cm3 would 81 grams of aluminum occupy?

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.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
