When a liquid or a gas occupies a volume, it may he assumed to fill the volume completely. On the other hand, when solid particles occupy a volume, there are always spaces (voids) among the particles. The porosity or void fraction of a bed of particles is the ratio (void volume)/(total bed volume). The bulk density of the solids is the ratio (mass of solids)/(total bed volume), and the absolute density of the solids has the usual definition. (mass of solids)/(volume of solids). Suppose 600.0 g of a crushed ore is placed in a graduated cylinder, filling it to the 184 cm^3 level. One hundred cm3 of water is then added to the cylinder, whereupon the water level is observed to be at the 233.5 cm^3 mark.

Calculate the porosity of the dry particle bed, the bulk density of the ore in this bed, and the absolute density of the ore.
