10.3 For a linear molecule of polyethylene of molar mass 119,980 g mol-¹, calculate: (a) the contour length of the molecule, (b) the end-to-end distance in the fully-extended molecule, and (c) the root-mean-square end-to-end distance according to the valence angle model. In the calculations, end groups can be neglected and it may be assumed that the C-C bonds are of length 0.154 nm and that the valence angles are 109.5°. Comment upon the values
