The reasons for this are threefold. Firstly, the bulk density of raw Microsilica, being almost as fine as cigarette smoke, is about 0.2 tonnes per cubic metre. The process of micropelletisation increases the bulk density to between 300 and 650 tonnes per cubic metre.
The gram formula unit mass of copper (II) sulfate pentahydrate is 249.68. The gram formula unit mass of water is 18.015. Therefore, the mass of water of crystallization presen â¦ t in 50.0 g of copper (II) sulfate pentahydrate is: 50[5(18.015)/249.68] or 18.0 g, to the justified number of significant digits. (Note that the prefix penta- means five)
