The CC valence bond angle is roughly 100°. Let's assume the CC bond distance d is 0.15 nm. The macroscopic density of linear polyethylene is around 1.0 g/cm³. 1.1. Determine the molar mass of the monomeric unit (also known as repeating unit) 1.2. Determine the degree of polymerization, n, of a chain with a molar mass of 500 000 g/mol. 1.3. Determine the contour length of the chain.
