No. They are not the same at all. The amount of space is volume. The amount of mass within a unit of volume is density.

So you could have a cube that measures 1 meter on each side. Its volume is one cubic meter.

But different substances that can fill that volume can be very different in weight. You can fill the cubic meter with feathers or you can fill it with books. A cubic meter of feathers weighs a lot less than a cubic meter of books. Books are denser than feathers. Books have a greater density than feathers.

Volume: the amount of space that an object or a substance fills; the amount of space that a container has
Ex: The teacher taught us how to measure the volume of a gas.
Ex: Jars of different volumes (Different sizes)
Volume: simply means the amount of sth
Ex: Sales volumes fell 0.5 in May.
Volume: used for the amount of sound that is produced by a TV, radio, etc.
Ex: It's so noisy! Could you turn the volume down?

Density: the quality of being dense; the degree to which is dense
Ex: Low density forest
Density (in Physics): the thickness of a solid, liquid or gas measured by its mass per unit of volume
Ex: The density of a gas
Density (in Computing): the amount of space available on a disk for recording data
Ex: A high density floppy
As you can see, density can be counted as volume, they may seem different, but somehow, they have a connection, don't they? It's up to the situation to choose which to use.
