What is a density bottle? How is it used to find the density of a liquid?

Question

KnowledgeBoat · Accepted Answer

A density bottle is a specially designed bottle which is used to determine the density of a liquid. The figure of density bottle is shown below: Determination of Density of a Liquid using the Density Bottle 1. Measure the mass of empty density bottle using a beam balance. Let it be M₁ g. 2. Remove the stopper of the bottle and fill it with water. Replace the stopper, wipe the outside of bottle dry and measure its mass again. Let it be M₂ g. 3. Empty the bottle and dry it. Fill it with the given liquid, replace the stopper and wipe the outside of bottle dry. Measure its mass. Let it be M₃ g. 4. Calculate the mass of water (M₂ - M₁) and the mass of liquid (M₃ - M₁). 5. Since density of water is 1 g cm^-3, mass of water contained in bottle is the volume of bottle. Thus, Mass of liquid = M₃ - M₁ Volume of liquid = M₂ - M₁
