Question

What is the volume of a sample that has a mass of 20g and a density of 4g/ml?

Answer 1

Volume = Mass / Density

So: 20/4 = 5ml

Hope that helps 

Answer 2

Answer: The volume of the sample is $5ml$

Explanation:

Density is defined as the mass contained per unit volume.

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

Given : Mass of object = 20  grams

Density of the object = $4g/ml$

Putting in the values we get:

$4g/ml=\frac{20g}{Volume}$

$Volume=5ml$

Thus the volume of the sample is $5ml$
