Answer:

You cannot convert mass to density. You can calculate density from mass and volume.

Explanation:

#D=M/V#,

where:

#D# is density, #M# is mass, and #V# is 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 #"5.42 g"# and a volume of #"3.19 cm"^3"#?

#D=("5.42 g")/("3.19 cm"^3)="1.70 g/cm"^3"#

Answer:

Well, if these are all the data you got you are a shot bird....

Explanation:

By definition, density, mass per unit volume, is given by the quotient...#rho_"density"="mass of sample"/"volume of sample"#.

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?
