What is the Difference Between Density and Concentration?ĭensity is the ratio between mass and volume of a substance while concentration is the ratio between the amount and volume of a substance. The volume concentration is the volume fraction of the considered compound from the total volume of all compounds before mixing. The unit of this is dm -3 (per cubic decimeter). Similarly, the number concentration is the number of molecules of the given compound in a unit volume. The unit of this definition is mol / dm 3. Moreover, the molar concentration is the number of moles of the given compound in a unit volume. Mostly, the units for this parameter is g / dm 3, but there are some other units as well. For instance, the mass concentration is the mass of the given compound in a unit volume. There are several types of concentrations that we can define. In a qualitative sense, concentration is the amount of a compound in a solution. What is Concentration?Ĭoncentration is another important concept in chemistry. This is the ratio of the two densities and is merely a number. Moreover, we can define the term relative density in order to compare the densities of two fluids. Thus, if the density of the fluid or the uniform solid is lesser than that of the given fluid, it will float on the given fluid. Here, the floatation means that a fluid or a uniform solid that is denser than a given fluid will drown in the given fluid. However, if the mass distribution is not even, we need more complicated methods to measure the density.įigure 01: A Density Column containing some Common Liquids and Solids with different Densitiesįurthermore, we can easily describe the floatation of a substance using its density. Density, in the most primitive form and it is the mass per unit volume.įor a bulk material with uniform mass distribution, we can easily calculate this parameter by dividing the total mass of the object by the total volume occupied. Accordingly, mass is a measurement of inertia of an object. Therefore, getting a clear understanding about it is vital to have a clear understanding of mass. Side by Side Comparison – Density vs Concentration in Tabular Formĭensity is an important characteristic of matter. Therefore, it is necessary to have a thorough understanding of such concepts before discussing the difference between density and concentration. The key difference between density and concentration is that the density of a substance depends only on the amount of matter within a given volume whereas the concentration depends on the amount of matter and what compound is in there, as well.ĭensity and concentration are two basic and important topics that we discuss under chemistry and material sciences.
