showing the composition and structure of a molecule. The atoms are represented by symbols and the structure is indicated by showing the relative positions of the atoms in space and the bonds between them:H–C≡C–H is the structural formula of acetylene. See alsoempirical formula,molecular ...
例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...

How to write the molecular formula of a compound. What is the name of the molecular compound BF3? How to find molecular formula of a compound? What is the molecular formula of benzene? What is molecular structure? What is the molecular formula for salt?
Figure 1. The average mass of a chloroform molecule, CHCl3, is 119.37 amu, which is the sum of the average atomic masses of each of its constituent atoms. The model shows the molecular structure of chloroform. Likewise, the molecular mass of an aspirin molecule, C9H8O4, is the sum of...
For the exhaustive and irredundant generation of candidate structures, two types of structure fragments, component and segment, are introduced in expert system for the elucidation of the structures of organic compounds system. A new scheme for the decomposition of the molecular formula into component ...
