Density

So you're wondering, what is density and why is it important? Well since my vocbalulary is too intense, ill dumb it down a bit and sum it up in a few words. Density is a physical property of matter specified as mass per unit volume.  It is important because if you have two objects that have the same size, you can differentiate the two by calculating density from the following pyramid.

Mass = Density x Volume

Density = Mass / Volume

Volume = Mass / Density

Being a student the stress with memorzing formulas, please consider this pyramid because it can save your life. It also works in physics.

Some ways to represent density:

For a solid : g/cmᵌ

For a liquid: g/mL

1cmᵌ of water = 1mL

*If you want to know if an object floats or sinks, look at this equation below.

ᵈobjects > ᵈliquid = sink

ᵈobjects < ᵈliquid =float

Now for an example to help you with your problems.

Ex. Calculate the density of a solid gold house that has a mass of 133337g and a volume of 137.7L

Density = mass/volume                                                       D=133337g/137.7L

                                                                                          D=968.32g/L

Coke sinks, Diet coke floats. Aint that cool?
