![]() Similarly, volume can be calculated by performing mathematical calculations based on the formula.īut, how can we measure the mass of the gas? We can use the concept of molar mass to measure the gas density.Īnother method to determine the density of liquids is the device called a hydrometer. A weighing scale can measure the mass of a substance in grams or kilograms. The main method to determine the density of a substance is to divide the mass by volume, as discussed above. But, do we know that how the density is measured? Let's discuss this in detail. We have discussed the density formula, and the density of materials. The above table clearly depicts the densities of various substances, where solids (aluminum and diamond) have high densities and gases (hydrogen and helium) have lowest densities. Substanceĩ58 - 1000 (the value can vary at different temperatures, but between the specified range) Let's consider the densities of few substances. The liquids generally have medium-density that lies between the solids and gases. It predicts that the gases have the least density and the solids have the maximum density. The atoms of the gas are very loosely packed and can move quickly in space. The atoms of liquids are loosely bound and can be transferred into any shape. We know that the atoms of the solid are packed more tightly than the liquids and gas. Let's discuss the density of solid, liquids, and gas. These materials have the lowest atomic weight and thus the least density. The materials with low density are categorized as grapheme, hydrogen, etc. The atoms of these substances are tightly packed around the nucleus. The denser materials are categorized as uranium, god, tungsten, platinum, etc. For example, a material with stuff or strong packaging in the space is denser than the loose packing material. Here, we will discuss the least and most dense materials. Here, we will discuss examples of density, measurement of density, measurement, units of density, Numerical examples, and MCQs based on the density formula. For example, osmium is the densest element known under standard conditions. Inspired by the inventions of the Archimedes on density, Galilio Galilei invented a hydrostatic balance that could measure the metal weights in air and water.ĭifferent materials exhibit different densities. He was an engineer, inventor, mathematician, physicist, and astronomer (studying celestial objects). The density formula was discovered by Archimedes. ![]() Thus, the unit of density can be kilograms per meter cube (Kg/m^3) or grams per centimeter cube (g/cm^3). ![]() V is the volume that is measured in meter cube (m^3) or centimeter cube (cm^3). M is the Mass that is measured in Kilograms (Kg) or grams (g). Density defines how tightly the molecules of the substance are packed together. The density formula can be represented as: Mathematically, we can define density as mass divided by volume. The density of a substance is defined as mass per unit volume.
