![]() If ethanol contains significant amount of water, it tends to behave more like water then a biofuel―especially when mixed with gasoline. Some of the sophisticated alcohol monitoring systems available today can even measure the water content in ethanol. You can also measure the density of ethanol using an alcohol monitoring system. The mathematical formula to measure the density is p = m/ v, wherein p refers to density, m refers to mass, and v refers to volume. In case of ethanol, its average density is 0.789 g/cm 3 at the temperature of 20 ☌. The density of a particular object or liquid is measured in g/cm 3. If the object floats on water, it means the density of the object is less than the density of water, and if the object sinks, it means that its density is more than that of water. It basically depends on how closely the atoms are spaced in a particular object or liquid. Density of Ethanol at Room Temperatureĭensity is defined as the mass per unit of volume. Its density has a crucial role to play in its myriad uses, which range from being a potent psychoactive drug in various alcoholic beverages, to an alternative fuel in various cars and machines. It is basically produced from grains which have a significant sugar content. Ethanol is derived from grains (such as corn) and grass varieties (such as switch grass). Ethanol, also referred to as ethyl alcohol or grain alcohol, is a colorless volatile liquid, widely used as a solvent of substances meant for human consumption or contact.
