10.3 For a linear molecule of polyethylene of molar mass 119,980gmol1, 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 CC bonds are of length 0.154nm and that the valence angles are 109.5. Comment upon the values obtained. Indicate, giving your reasoning, which of the very large number of possible conformations of the molecule is the most stable
