Answer Details
To accurately measure the relative density of a substance in its powdered form, a density bottle is used. A density bottle is a specialized glass bottle designed to hold a specific volume of liquid at a specific temperature. By measuring the mass of an empty density bottle, then filling it with the powdered substance and measuring the mass again, the mass of the substance can be determined. The volume of the substance can then be determined by filling the density bottle with a liquid of known density, such as water, and measuring the mass again. The relative density can then be calculated as the mass of the substance divided by the mass of an equal volume of water.
