When a liquid or a gas occupies a volume, it may be 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 cm3 level. One hundred cm3 of water is then added to the cylinder, whereupon the water level is observed to be at the 233:5 cm3 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
