Question

What is the density of an unknown object that has a mass of 5.0 g and volume of 20
ml?

Answer 1

Answer:

Density=mass / volume.

Density = 5/20.

0.25g/cm^3.

Answer 2

The density of the unknown object is 0.25 mL

Density of an object is defined as the mass of the object per unit volume of the object. Mathematically, it can be expressed as:

$Density = \frac{mass}{volume}$

• With the above formula, we can obtain the density of the unknown object as follow:

Mass = 5 g

Volume = 20 mL

Density =?

$Density = \frac{mass}{volume} \\ \\ Density = \frac{5}{20} \\ \\ Density = 0.25 \: ml$

Therefore the density of the unknown object is 0.25 mL
