Type your answers in all of the blanks and submit Solve the ideal gas equation for both molarmass(MM) and density. Let's do this in a series of steps. First think about the equation for molar mass (MM = m/mol) and isolate the moles. Type your answer here Type your answer here n3= Now plug the equation for moles into the ideal gas law (PV = nRT). Type your answer here Type your answer here PV = Now rearrange this equation to isolate the molar mass (MM). 13 M = Type your answer here Type your answer here And finally, rearrange the equation and isolate the variables for density. Remember that density = m/V. E Fur d = Type your answer here Type your answer here

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 -…
