A block of brown sugar has a volume of 8 #cm^3# and a mass of 12g? What is the density of the brown sugar?
Bulk density would be 1.5 g/
The density will be mass divided by volume, which in this case is 12/8 or 1.5 g/
However, if the block is comprised of compressed granules of sugar, then this figure is the bulk density, not the volumetric mass density.
Bulk density is not an intrinsic property, and can change, for example, if the granules are more tightly compressed. If you took the same 12 g of sugar and compressed it harder to make a smaller more compacted block, then the bulk density would increase.
