The equation for density is: Density = mass/volume or D = m/v. Each substance has its own characteristic density because of the size, mass, and arrangement of its atoms or molecules. Step 4 Show ...

The formula of the law of conservation of mass is as follows: ∂ρ/∂t +⛛(ρv) = 0. Where, ρ = density. t = time. v = velocity ⛛ = divergence. What is the Law of Constant Proportions?

Mass is measured in grams. The units for density will be g/cm³. Image Metal. Download Image. Arrangement of atoms in different metals is similar. Individual atoms are packed very close together.
