The concept of density was invented, not discovered. It was invented by thinkers
who needed a way to describe the weight of a substance that depends only on
the substance, and not on how much of it you have.
*Remember: D=<3 (Love) Density=Mass/ Volume (D=M/V ... it looks like a heart when you write it)
Archimedes, of course in his day he was termed a philosopher.

Palladium, discovered by William Hyde Wollaston in 1803, is a chemical element with a density of 12.02 and atomic number of 46. It is actually the least dense metal of the platinum group metals, which include rhodium and iridium.
That element would be Scandium. It's abbreviation is Sc it was discovered in 1879. It has a density of 2985 kilograms per cubic meter.
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Let's look at this. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Liquid water has a maximum density at about 4 °C. And there is 1 gram in a cubic centimeter or a milliliter of water. We say water has a density of 1 gram/cubic centimeter. Other substances can have their mass discovered when a known volume is weighed, and then the density of those substances can be discovered and recorded. Specific gravity is a comparison of the density of a substance to the density of water. The specific gravity of a material will not have units associated with it. It is a purenumber. If a substance has a spee gee (lab speak for specific gravity) of 2, it will have 2 times the density of water. A cubic centimeter of this material will weigh 2grams, and will have a density of 2 grams per cubic centimeter. But, to repeat, spee gee has no units associated with it. The only time that specific gravity and density will have the same value is when the substance under inspection has the same density of water at 4 °C. That's the only time density and spee gee will have the same value. And note that we're talking value here, and without regard to units. Density has units of mass per unit of volume, and specific gravity has only a numerical value, only magnitude, and nounits associated with it.
Its density. Density is mass per unit volume.
Archimedes discovered density in 265 BC, when he was only 22. He discovered density when he was taking a bath. He discovered that the deeper he went he weighed less and the more the water ran out.
He discovered that you have to find the volume, mass, and density of something
Archimedes
The principle of density was discovered by Archimedes. To calculate density, we use the equation Density = mass/volume.
Archimedes
No he discovered density
it was discovered in 1234
discovered at the Lawrence Berkeley National Laboratory.its discoverer, cell biologist Richard Schwarz
i don't know who but it is about someone who put them self in a bath tube and he noticed the water went up and that is how much density you took up in the world.

Density. Its considered a physical property because of the amount of mass/volume. Its an intensive physical property because you can measure density of solution without changing its chemical identify, it observable. ... Because a material that expands takes up a larger volume and it density decreases.Dec 10, 2014
The planet that has enough density to support the weight of a colony is Mars. Scientists have discovered that Mars is relatively similar to the conditions on Earth.
