Question

A piece of aluminum has a volume of 150 cubic centimeters and weighs 405 grams. What's its density?

A. 3.36 g/cm3
B. 3.03 g/cm3
C. 4.05 g/cm3
D. 2.70 g/cm3

Answer 1

The answer is D. 2.70 g/cm3

Density is calculated with the equation

d = m / v

in this case, d = 405g / 150cm3 = 2.7 g/cm3

Hope this helped!
