a) (1 point) As mentioned in Question 2, methyl methacrylate (sketched at right) H undergoes linear addition polymerization to form a common polymer. Assuming the polymerization runs to completion, how many kilograms of this molecule are needed to produce 625 kg of the polymer of part g)? Answer: b) Data on the molecular weight distribution of a specimen of the polymer from part g) are tabulated at right. Compute the following properties of this specimen. Assume that the answers will be valid to three significant figures. Show your work below.
