Question

The density of aluminum is 2.7 g/cm3. What is the volume of a piece of aluminum if its mass is 8.1 grams?

Answer 1

To find the volume of a piece of aluminum with a mass of 8.1 grams and a density of 2.7 g/cm³, calculate the volume by dividing mass by density, giving you a volume of 3 cm³.

Step-by-step explanation:

The density of aluminum is given as 2.7 g/cm³. If the mass of a piece of aluminum is 8.1 grams, you can calculate its volume using the formula density (p) = mass (m) / volume (V). In this case, you would rearrange the formula to solve for volume, resulting in V = m / p. Plugging in the known values, we get V = 8.1 g / 2.7 g/cm³.

After performing the division, we find the volume of the piece of aluminum is 3 cm³. Thus, the piece of aluminum has a volume of 3 cubic centimeters for its mass of 8.1 grams when the density is 2.7 g/cm³.

Answer 2

density = 2.7g/cm3
mass =8.1grams
from density =(mass)/volume
we can determine the volume of aluminium by simply changing the subject of the subject of the formula from density to volume
so we have

volume=mass/density
=(8.1grams)/(2.7g/cm3)
=3cm3
