Details of the 18 constitutional isomers of C8H18 (and the accompanying R/S 'optical' isomers) Isomers (1) to (4) are illustrated above, their abbreviated condensed formula and skeletal formula, together with the appropriate carbon atom chain numbers of the C8H18 isomer.

化学式 C8H18 即 辛烷，总共有24种 同分异构 体，若不考虑 立体异构 则为18种：

First, compute the number of each atom in C 8 H 18: C: 8, H: 18. Then, lookup atomic weights for each element in periodic table: C: 12.0107, H: 1.00794 Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (C 8 H 18) = ∑ Count i * Weight i = Count(C) * Weight(C) + Count(H) * Weight(H) = 8 * 12.0107 + 18 * 1 ...
