Question

A block of metal has dimensions of 2.00 x 5.50 x 1.25 cm. It has a mass of 37.1 grams. What is its density?

-512 g/cm3
-0.372 g/cm3
-2.69 g/cm3
-4.24 g/cm3

Answer 1

2.69 is the correct answer

Answer 2

Density = 2.69 g.cm⁻³

Solution:

Data Given;

Density = ??

Mass = 37.1 g

Volume = 2.0 cm × 5.5 cm × 1.25 cm = 13.75 cm³

Formula Used;

Density = Mass ÷ Volume

Putting values,

Density = 37.1 g ÷ 13.75 cm³

Density = 2.69 g.cm⁻³
