Abstract Knowing the theoretical density of a particular object is often not ideal in certain situations and applications. Though they may be made a single substance, the majority of “solid” objects are still porous which could create inaccurate results in experiments or undesired results in selection. The density of a sample was determined by measuring its volume and measuring its weight in air as well as its weight in a liquid. Using the theoretical density, the porosity of the sample can be calculated. Introduction The density of an object is typically found simply by dividing the mass by the volume. Yet that method is flawed if the particular sample is porous, which a majority of substances are. It is relatively simple to find the volume of a simple shape and then to find its mass to find the density. When the sample has an odd shape, other methods must be used. In the situation in which the volume cannot be found easily, the sample can be
