Computer Compilation of Molecular Weights and Percentage Compositions for Organic Compounds presents the outputs of computer programs that calculate the molecular weights and percentage compositions of organic compounds. The data presented in the text only covers compounds containing carbon, hydrogen, and heteroatoms, while the elements covered are bromine, chlorine, fluorine, iodine, nitrogen, oxygen, and phosphorus. The calculations of the result were conducted by Control Data Corporation 1604 computer. The book will be of great use to chemists and chemical engineers who need to have a quick access to the data on organic compounds.
