What is the relationship between density and mass?

Answer 1

Mass and densityDensity is defined as mass per unit volume. For example, the kilogram is the fundamental SI unit of mass. The kilogram per cubic meter and the gram per milliliter are examples of units of density.

The concept of density's relationship with weight maybe that when considering two objects with same mass (i.e same quantity of matter contained) and same volume(i.e same space occupied);the one with the greater density(more denser) will be more heavier than the less denser object .This depends upon the different materials they are made up of.the denser object is more in weight probably (that is what i conclude) due to the absence of any other medium molecules in between the molecules of the material (in the molecular space)that constitutes the object unlike the less denser object which may have other surrounding medium's molecules in the intramolecular space......because practically there no vaccum in the intramolecular space of a particular gas but there are molecules of air between them

Answer 2

Density is a measure of how much mass something has per unit of volume. Therefore, if you increase the mass of an object without increasing it's volume, it's density will also increase. Likewise, decreasing the mass of an object that keeps a constant volume leads to a decrease in density.

Answer 3

Density = mass / volume
