Mathematical Definition of Density: The formal definition of density is mass per unit volume.Usually the density is expressed in grams per mL or cc. The densities of some everyday substances are: Steel has a density of 7.82 g/cm³. cc is a cubic centimeter and is equal to a mL Therefore, Conversion Factor in Chemistry: Definition, Formula & Practice Problems 6:47 Density: Definition, Formula & Practice Problems 3:19 4:35 Density values. DENSITY DEFINITION. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Air has a density of 0.0013 g/cm³. Water has a density of 1.00 g/cm³. Definition of Density 1) Mass per unit Volume: D=MV 2) The ratio of mass to unit volume expressed in grams/cm3 for solids and liquids and grams/liter in gases (density=mass/volume). Mathematically a "per" statement is translated as a division. Density is defined as mass per unit volume. Density is an intensive property of matter, which means the size of a sample does not affect its value. The mass of atoms, their size, and how they are arranged determine the density of a substance. Density, mass of a unit volume of a material substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density allows you to solve for mass and volume if given the other quantity. The symbol most commonly used for density is ρ (the lower case Greek letter rho).The capital letter D is also used.
Density equals the mass of the substance divided by its volume; D = m/v. Density is commonly expressed in units of grams per cubic centimetre. (Note that the asterisk symbol—*—is used to avoid confusion with the variables for volume and density, ρ and v, respectively.) Since the density of common substances is known, this calculation is fairly straightforward, in the form. Density is a characteristic property of a substance.
