Measuring the Density of Irregularly Shaped Solids

Irregularly shaped solids do not have regular dimensions and therefore cannot have their volumes calculated with a formula. Rather, we determine their volumes by water displacement (assuming that they do not dissolve in water). This means that the volume of water a solid displaces upon complete immersion is equal to the volume of the solid. In the laboratory, the process is as follows  

A quantity of water is added (to a volume significantly less than the capacity of the cylinder but enough so that the solid can be completely immersed). 

The solid is immersed (being careful not to splash any water out of the cylinder and not to trap any air under or within the solid). 

What is the density of an irreguiariy shaped piece of metal given the foliowing data mass = 173.03 g.watervoiume beforeimmersion = 27.8 mL, water volume after immersion = 43.9 mL
