[QUOTE="d.arbitman, post: 4628069, member: 413086"] [h2]Homework Statement [/h2] Please see attached for problem statement and table of bond energies. My chemistry background is awful and this is from a materials science textbook. The question is, how would I approach/solve 2.31 (only parts b and c).[h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] We go from two double bonds (C= C) and a single bond (C - C) to two single bonds (C-C) and one double bond (C= C) (2*3.7E5 + 6.8E5) - (2*6.8E5) = 60 kJ/mole The molecular mass of the 'mer' is 88.53 g/mole. 1kg/88.53g = 11.30 moles 60 kJ/mole * 11.30 mole = 678 kJ I know both of these are the correct answer, but I just need verification of my problem setup. Thanks. [/QUOTE]
