Alcohol Etílico Densidad [repack]

At face value, the density of pure ethyl alcohol appears straightforward. At standard temperature and pressure (20°C), absolute ethanol has a density of approximately 0.789 g/cm³. This figure immediately establishes ethanol as "lighter" than water, which has a density of roughly 1.00 g/cm³. On a molecular level, this disparity is explained by mass and packing; water molecules, though lighter individually (18 g/mol versus ethanol’s 46 g/mol), are polar and small, allowing them to pack tightly together through hydrogen bonds. Ethanol molecules are bulkier due to their non-polar ethyl group, creating structural hindrance that prevents them from achieving the compact density of water.

Ethyl alcohol expands with temperature much faster than water does. A hydrometer calibrated for 20°C will lie to you if you test a warm spirit at 30°C. It will read a lower alcohol content than what is actually present because the hot liquid has expanded, lowering its density. alcohol etílico densidad
