Question

What is the density of a substance that has a mass of `5` `g` and a volume of `40` `cm^3`?

Answer 1

It would be `(5g)/(40cm^3)=0.125g//cm^3`

Explanation:

In SI units you want to use `kg//m^3`:

`(0.125g)/(cm^3)=(0.125gxx1000)/(cm^3xx1000)=0.125kg//dm^3`

`(0.125kg)/(dm^3)=(0.125kgxx1000)/(dm^3xx1000)=125kg//m^3=125kg*m^(-3)`
