I only need help with part a,e and question 2. please check part a a few times before answering, some of the responses on here are wrong and all display the same value. Thank you.

1. Polyethylene is made up of the following fractional distribution. Fraction Molecular Weight (Da) Number of chairs 1000 1. 5,000 10,000 1000 1,000,000 3 a. Calculate the weight average molecular weight (MW) of the polymer. (4 pts) b. Calculate the number average MW of the polymer. (4 pts) c. Calculate the poly dispersity. (2 pts) d. Which average molecular weight determination did the fraction 3 most significantly affect and Why? (2 pts) e. What would be the volume of a sample (100g) if the density of the polymer is 0.95 g/cc? (4 pts) f. What is the best way of making this polymer: free radical, condensation, etc? (2 pts) 2. A sample of methacrylate (CH=CHCOOCH3) is polymerized, the resulting polymer has a degree of polymerization of 1000. Draw the structure for the repeating unit of the polymer (2 pts) and calculate the polymer's molecular weight (6 pts). Bonus: For a specific polymer, which of the following forms (isotactic, syndiotacytic, and atactic will likely be amorphous? (2 pts) 23
