Question

What is the density of a substance with mass 200g and volume 25mL?

Answer 1

`rho=8` `g//cm^3`

Explanation:

Density is given by the ratio of a(n) object/substance's mass to volume.

`rho=m/v`

Typical units of density are `kg//m^3` and `g//cm^3`. Because we are given the mass in grams and the volume in milliliters, we'll use `g//cm^3`. One mL is equivalent to one cubic centimeter.

Therefore, we have:

`rho=(200g)/(25cm^3)=8` `g//cm^3`

The density is `8` grams per cubic centimeter.
