Does everyone know the SI unit, symbol and name for mass density, and
what it is the density of?

The term "mass density" means different things in different contexts.

The density of mass is a measure of a substance's mass per unit of volume

rho (density) is defined as mass per volume, p = m/V

In SI units that is kg/meter^3 (kilogram per cubic meter)

Density is a ratio. It is mass over volume each of which has a perfectly

Wow. You can't even pose a semi-intelligent question.

There is none. A derived unit might be kg/m^3.
I'd have to look regarding the name thereof.

Good Heavens; don't do anything drastic.

I was just wondering what the kg/m^3, SI mass density applied to: Like
would it be the mass density of platinum or lead or something? Nobody
seems willing or able to answer so I guess I'll just have to write to
the people who know: Like NIST, the U S Metric Association, or maybe
the archives at Sevres France. Think they know(;^?

Dumb Donny shitHead, you are a terrible idiot. Contract for a seat in
public school physics. Density is intensively covered around 4th
grade. Archimedes correctly worked it through his head in ~240 BC.
