How to Calculate Unit Weight
Sep 04, 2019Soil is a product commonly sold by unit weight. Soil consists of dirt, water and organic matter. The dry unit weight of soil is a helpful figure as it can be used to establish a standard of sale between a purchaser and a soil vendor. It can be measured after when the void spaces of the soil (which are sort of like the holes in a sponge) are filled with air, with no water remaining. Get price
Polymers
Many polymeric materials having chain-like structures similar to polyethylene are known. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following table.

Crystal Structure of Cesium Chloride
Crystal Structure of Cesium Chloride. The ionic radius of the cesium ion is 1.88 and that of the chloride ion is 1.67 . In this case the cation is the larger ion, and the ratio of radii for the anion and cation is r-/r + = 1.67/1.88 = 0.888.. With a radius ratio of 0.888, the smaller ion (Cl-) is expected to prefer a cubic hole.. The images below depict the structure of crystalline CsCl. Get price
