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

  6. Density (article) | Khan Academy

    Density is defined as the amount of mass per unit volume, as shown in the equation below: To calculate density, simply divide mass by volume. In chemistry, mass is typically measured in units of grams (g) …

  7. What Is the Definition of Density in Chemistry?

    Density is quantitatively expressed as the ratio of an object’s mass to its volume, represented by the formula: Density = Mass / Volume (D = m/V). To determine a substance’s density, both its mass and …

  8. Density - Definition, Formula, Units and Calculations | CK-12 Foundation

    Dec 1, 2025 · Since a cubic centimeter is equal to a milliliter, density units can also be expressed as g/mL. Gases are much less dense than solids and liquids, so their densities are often reported in g/L. …

  9. What does density mean in chemistry? - California Learning Resource …

    Apr 6, 2025 · Density (ρ) is defined as the mass (m) of a substance divided by its volume (V). The equation representing this relationship is: ρ = m/V. The standard SI unit for density is kilograms per …

  10. Density - Physics Book

    Dec 2, 2025 · Density describes how much mass is contained in a given volume. It is a measure of how “packed” matter is. Formally, density is usually written with the Greek letter ρ (rho), and in some …
