Density = mass divided by volume, measured in kg per cubic metre
There is not necessarily any direct relation between mass and volume unless the mass is cross-referenced with density.
Depending on how you interpret the question, the relationship between those two properties either nonexistent or trivial. Volume is an extrinsic property and density (ratio of mass to volume) is an intrinsic property; there's no relation between them other than IF you know any two of the three properties (mass, volume, density) you can calculate the missing one.
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
Density is calculated by dividing an object's mass by its volume. The more mass an object has in relation to its volume, the higher its density will be. Conversely, if an object has a larger volume relative to its mass, its density will be lower.
The ratio between mass and volume is density.
mathematics and physics
The relation between mass(M), density(ρ) and volume(V) is given by: M = ρ x V. So mass can be calculated only if both density and volume are known. Density is a measure of amount of substance per unit volume, so mass can't be calculated until the volume of substance is known.
mass / volume is density.
Density = Mass / Volume Mass = Density * Volume Volume = Mass / Density
The mathematical relationship between mass 'm' and volume 'V' is that the ratio of these two quantities is equal to the density. The ratio of a substanceâ??s mass and volume is given as mass per unit volume. Density is a physical property of a substance.
For any object, the mass is the product of its volume and its density. In the case of Earth, that would be the averagedensity. The volume, of course, can be calculated on the basis of its radius. Use the formula for a sphere; that's close enough for most purposes.
The period is independent of the mass.
