Avagadro’s number

Number of moles of A,B in the sample = N7Av, where Av = Avagadro s number. 

One equivalence of electrons is 1 g mol of electrons or 6.022 xlO electrons (Avagadro s number). This quantity of electrons has the charge of 96,487 coulombs (C) (Faraday s constant). Thus, the charge of a single... 

The quantity e0B is the energy of the lowest state of B, and e0A is the energy of the lowest state of A. As it is more convenient to have energies on a molar basis, we multiply the energies and the Boltzmann constant by Avagadro s number, N0, and since kN0 is equal to the gas constant R, 1.986 cal °K mole-1, we obtain Equation A 1.3 ... 

The quantum energies are put on a per mole basis (energy of Avagadro s number of quanta) for convenient comparison with molar bond dissociation energies. Refer to Section 13.1 for further discussion. 

Amedeo Avogadro developed the hypothesis that equal volumes of different gases contain an equal number of molecules, if the gases are at the same temperature and pressure. The proportionality between volume and number of moles is called Avagadro s Law, and the number of molecules in a mole is called Avagadro s Number. Both were posthumously named in his honor. 

It follows from eqn. (34) that, provided nbIN0 < C (where N0 is Avagadro s number) and dH is small... 

Avagadro s number, molecules per kilomole. number of holes in the lattice, number of molecules of component i. surface area parameter for the lattice, pressure, pascals, reduced pressure, characteristic pressure, pascals, surface area parameter of component i. group area parameter for group k. partition function. 

Mole A mole of a particular substance is equal to the number of atoms in exactly 12 g of the carbon-12 isotope. See also Avagadro s number. 

In Equations 6-10 d0 is the density of the solvent which was measured at each solvent composition at each temperature, a is the ion-size parameter, z is an empirical constant, N is Avagadro s number, D is the dielectric constant of the solvent, k is the Boltzman constant, and e is the electronic charge. Other terms have been defined already. 

Equation (27) (N = Avagadro s number rj = refractive index c = velocity of light) implies that A/xrp and Hrp are constant over the absorption band (Condon approximation). A closely related expression, equation (28), can be used for the emission intensity. 

Here V is the molal volume of the liquid, N is Avagadro s number, K the. Boltzmann constant, T the absolute temperature, and is the angle between the vectors jj, and Ji. ag is the polarizability of the molecules in the liquid it can be determined from the refractive index. For highly polar substances is small compared to the second term in the parenthesis. The high dielectric constant of water is well accounted for by equation (47) on the basis of the known dipole moment of water, and the orientation of the water molecules relative to one another. The molar polarization of the liquid is defined in terms of the polarizability and the dipole moment of the molecules by equation (47). In a solution containing several components equation (47) becomes... 

The polarizabilities of Ag and Au are found after the method of Bockris and Swinkels, where a , = 3 K ,/47tAav Vm is the molar volume and is Avagadro s number. They found for mercury that the calculated a , diifers from the experimental value by 14% so they correct the calculated Pt value by this amount the same was done here. 

N - Avagadro s number a - fluid polarizability - fluid dipole moment...
