Measurement of the density of a liquid at atmospheric pressure and temperatures near to ambient can readily be conducted with a specific gravity bottle to an accuracy of better than 177;0.1%. The device merely consists of a small glass bottle with an extremely accurately calibrated volume, which is weighed empty and then filled with the liquid.
Aug 24, 20180183;32;Theory. Density: The density of a substance is defined as the mass per unit volume,D= Here, D = Density of the body M = Mass of the body V = Volume of the body. S.I. unit of density = Kgm 3 or Kg/m 3 c.g.s. unit of density = g/cm 3 or g cm 3; Floating bodies: The density of water is 1 g/cm 3 and 1000 kg/m 3 . Case If the density of a body is more than 1

The determination of density is a nondestructive physical process for distinguishing one substance from another. Density is the ratio of a substance's mass to its own volume. volume mass V m d = = In the metric system the unit of density for a liquid or solid is measured in g/mL or g/cm3. The cm3File Size: 40KB

definition of float). Each student then determines the density of the groups salt solution by using both a pipet and a graduated cylinder. They compare the results to determine the effect that the volume measuring device has on calculating the density. Students also explore how the freshness of the raw egg affects their results.
