Question

Aluminum has a density of 2.7 g/cm³. If a block of aluminum has a volume of 15.0 cm³, what is its mass?

a) 40.5 g
b) 20.7 g
c) 45.0 g
d) 37.5 g

Answer 1

The mass of a 15.0 cm³ aluminum block, with a density of 2.7 g/cm³, is 40.5 grams.

Step-by-step explanation:

The mass of a block of aluminum can be found by multiplying its volume by its density. Given that the density of aluminum is 2.7 g/cm³ and the volume of the aluminum block is 15.0 cm³, we calculate the mass by multiplying these two values:

Mass = Density × Volume = 2.7 g/cm³ × 15.0 cm³ = 40.5 g

Therefore, the mass of the 15.0 cm³ aluminum block is 40.5 grams.
