Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Case Study - Bottling a Carbonated Drink The process of dissolving carbon dioxide (CO,) in water in known as carbonation. The presence of this gas creates bubbles and fizzing in the water. This process can occur naturally in some instances (e.g, beer) or artificially by injecting the C0, gas into the water under pressure. The process for artificially dissolving CO, was discovered in the 1776 but wasn't commercialized until 1807. Since then, the market for carbonated drink has consistently grown. Currently, carbonated drink can be found all over the world and are typically packaged using metals (aluminum), ceramics (soda-lime glass) and polymers (plastic #1). Perform an analysis of each of these materials. List the pros and cons of each and ultimately determine which of these materials is best considering the requirements listed below. 1) Keep the CO, - who wants to purchase a flat soda 2) Be non-toxic and chemically unreactive- this is meant for human consumption 3) Be inexpensive -…
