How do you convert mass to density?
You cannot convert mass to density. You can calculate density from mass and volume.
If you known mass and volume, you can calculate density.
Example: What is the density of a sample of aluminum with a mass of
Well, if these are all the data you got you are a shot bird....
By definition, density, mass per unit volume, is given by the quotient...
And so you need a measurement of the volume of the sample. For solids, liquids, and gases, what is your estimate of their relative densities?
