Homogeneous vs mixtures
The formula ρ = m/V hides whether you averaged over voids or multiple phases. Alloy densities are often handbook tabulations—not a naive mass divided by ruler volume—unless the sample is genuinely uniform through the bounding surface you measure.

Formulas
Density formula?
ρ = m/V for mass and the volume tied to that mass.
kg/m³ vs g/mL?
1 g/mL = 1000 kg/m³—the density unit menu handles conversion.
g/cm³ vs g/mL?
Same numerical value under standard lab equivalences taught with water.
