Sоlids mаy hаve аn irregular shape rather than a regular geоmetric shape. In that case its vоlume can be measured by displacement of a liquid, as shown in the figure below. (In the illustration, the volume of the solid would be 40.0 mL − 20.0 mL = 20.0 mL or 20 cm3). For this method to work the solid must (a) be more dense than the liquid, and (b) not react with nor dissolve in the liquid. Water is a suitable solvent for determining the volume of metals. An irregular shaped piece of metal has a mass of 132.6 g. You put it into a 100 mL graduated cylinder containing 26.0 mL of water, and the water level rises to 74.2 mL. The density of the metal is [density_to_3_sigfigs] as reported to [density_sig_figs] significant figures. If the initial volume of water was inadvertently written down as 26 mL (instead of 26.0 mL) then you would report the density as [density_to_2_sigfigs] g/mL.
