Structure and properties Index of refraction, n D: 1.000449 at 589.3 nm and 0 °C [1]: Dielectric constant, ε r: 1.60 ε 0 at 0 °C, 50 atm : Average energy per C=O bond : 804.4 kJ/mol at 298 K (25 °C) [2]
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
For example, Paraffin has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

The molar mass constant, usually denoted by M u, is a physical constant defined as one twelfth of the molar mass of carbon-12: M u = M(12 C)/12. [1] The molar mass of an element or compound is its relative atomic mass (atomic weight) or relative molecular mass (molecular weight or formula weight) multiplied by the molar mass constant.
[2] [3] In solution, there are two isomers known that rapidly interconvert: [5] The major isomer (on the left in the above equilibrium process) contains two bridging carbonyl ligands linking the cobalt centres and six terminal carbonyl ligands, three on each metal. [5] It can be summarised by the formula (CO) 3 Co(μ-CO) 2 Co(CO) 3 and has C 2v ...
Arlene Phyllis Klasky (born May 26, 1949) is an American animator, graphic designer, producer and co-founder of Klasky Csupo with Gábor Csupó. [1] In 1999, she was named one of the "Top 25 Women in Animation" by Animation Magazine. She is most known for her work with Nickelodeon in the 1990s and 2000s.
