Q5. When synthesizing and analyzing polymers, it is imperative that one understands the molecular weight from a biological perspective. a) Polyethylene glycol (PEG) is a polymer that is commonly used in a variety of research, biological, and pharmacological applications. Using the chemical structure below, calculate the molecular weight of the molecule with 76 individual monomers comprising the polymer. What is the molarity when 0.24 grams is added to 2.4L of deionized water ( 5pts) ? b) Is PEG considered an unsaturated polymer in the image above? Is it linear or branched (2 pts)? c) As mentioned above, polyethylene glycol is used in a variety of applications. In less than 125 words, cite a research article describing a use for PEG, summarizing how the PEG was used for the researchers. Credit will be given for a well-thought-out summary (17 pts)
