How do you calculate density of matter?

Answer 1

Mass per volume unit is the definition of density.

Consequently, the first step in determining an object's mass is to weigh it.

The next step is to determine the volume. If the object has a regular shape, like a block, you can compute its length, width, and height. If not, you can immerse it in water (in a graduated cylinder) and observe the variation in water level.

After that, it's: density=mass/volume, or #rho=m/V#
Extra: Officially, density is expressed in the unit #kg//m^3#, but as this would lead to high figures (water has #rho=1000 kg//m^3#), often the density is expressed in #kg//dm^3 or g//cm^3# (they have the same numerical value). So mercury would have an official density of #13.6*10^3 kg//m^3# but usually this is just abbreviated to #13.6# (this is called relative density, water being 1)

Answer 2

Density is calculated by dividing the mass of an object by its volume. The formula for density (ρ) is:

ρ = mass / volume

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
