What do we know:
What do we want to find ⇒ Density
To solve that,
⇒ must find the relationship between density, mass, and volume
⇒ Density = mass / volume
Now let's convert some units to make it into a standard answer:
(1 cubic meter = 1000000 cubic centimeter)
⇒ Density = 0.1 / 0.000048 = 2,083.33 kilograms per cubic meter
Hope that helps!
