| 1. | It is the gas constant divided by the Avogadro constant:
|
| 2. | The value of the Avogadro constant " N"
|
| 3. | A is the Avogadro constant, approximately 6.022 mol & minus; 1.
|
| 4. | As with a definition based upon carbon12, the Avogadro constant would also have been fixed.
|
| 5. | All silicon-based approaches would fix the Avogadro constant but vary in the details of the definition of the kilogram.
|
| 6. | The USSA1976 acknowledges that this value is not consistent with the cited values for the Avogadro constant and the Boltzmann constant.
|
| 7. | With this approach, the Avogadro constant would not only be fixed, but so too would the atomic mass of 28 Si.
|
| 8. | However, the USSA, 1976 does recognize that this value is not consistent with the values of the Avogadro constant and the Boltzmann constant.
|
| 9. | The molar attenuation coefficient ( in units of cm 2 ) is directly related to the attenuation cross section via the Avogadro constant N A:
|
| 10. | To find the van der Waals volume of a single atom or molecule, it is necessary to divide by the Avogadro constant " N ".
