Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D …

Jan 15, 2026 · Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of gram per cubic …

This lesson explains density as the physical property in chemistry that quantifies how mass is concentrated in a given volume. Gain a comfort using the formula D = m/V and explore how density …

Density is a physical property found by dividing the mass of an object by its volume. Regardless of the sample size, density is always constant.

Dec 2, 2025 · These differences in density explain everyday phenomena like floating and sinking, as well as engineering choices such as why airplanes are not built out of very dense metals.

Feb 5, 2020 · Density is how much mass fits in a certain volume, like grams per cubic centimeter. To find density, divide the mass by the volume of an object using the formula density = mass/volume. …

In this tutorial, you will learn what density is, & how to calculate it - along with the units, formula and equation for density.

Section Summary Density is the mass per unit volume of a substance or object. In equation form, density is defined as ρ = m V. The SI unit of density is kg/m 3.

Free online density converter - converts between 42 units of density, including kilogram/cubic meter, gram/cubic centimeter, kilogram/cubic centimeter, gram/cubic meter [g/m^3], etc. Also, explore many …

The density of gold, for example, is about 2.5 times the density of iron, which is about 2.5 times the density of aluminum. Density also reveals something about the phase of the matter and its substructure.
