Question

Aluminum has a density of 2.7 grams per cubic centimeter. What is the mass of a piece of aluminum with a volume of 40 cubic centimeters?

A. 21 g
B. 57 g
C. 96 g
D. 108 g

Answer 1

Option D. 108 g

Explanation:

we know that

The density is equal to the mass divided by the volume

D=m/V

Solve for the mass m

m=D*V

we have

D=2.7 g/cm³

V=40 cm³

substitute

m=(2.7)(40)=108 g
