where N0 is

Avogadro's number, Mw is weight average molecular weight, which can be measured through a GPC, and [[eta]] is the intrinsic viscosity which can be calculated by measuring solution viscosity of a polymer at various concentration levels.

The Six.02 Bioservices name reflects

Avogadro's number (6.023 x 1023), defined as the number of atoms or molecules per mole of any substance.

Vh is the hydrodynamic volume, Mw is the mol weight from LLS, [n] NA is the

Avogadro's number. The Rh can be calculated from Vh and the ratio of the geometric-to-hydrodynamic radii n can be determined as follows:

here, x is the overall monomer conversion, t the time (min), [k.sub.p] is the propagation rate constant (L[mol.sup.-1] [s.sup.-1]), [M.sub.p] the monomer concentration inside the particles (mol [L.sup.-1]), n the average number of radicals per particle (-), [N.sub.p] is the total number of polymer particles ([L.sup.-1]), V the total reaction volume (L), [M.sub.T] is the total monomer to be fed (mol), and Nm is

Avogadro's number ([mol.sup.-1]).

Avogadro's number is the number of atoms or molecules in one mole of a substance.

A more precise definition of

Avogadro's number (the number of atoms or molecules in one mole of a substance) strengthens the definition of Planck's constant, the value that will set the size of the kilogram in the revised standard of measurement.

where C is the activity concentration in Bq/kg, [M.sub.w] is the molecular weight (g/mol), N is

Avogadro's number, and [t.sub.1/2] is the half-life in seconds.

where M = [[SIGMA].sub.i][A.sub.i][n.sub.i] is the molecular weight of the sample, Ai is the atomic weight of the ith element, [n.sub.i] is the number of the formula units of a molecule, and [N.sub.A] is the

Avogadro's number. Effective atomic cross section, [[sigma].sub.a], has been calculated using the following equation:

For constant pressure and almost constant temperature, T, the above expression means that volume, V, is directly proportional to the number of moles liberated, n, but note that n = N/N[alpha], where N is the number of molecules and [N.sub.[alpha]] is

Avogadro's number. Both N and n are proportional to the number of bonds broken during electrolysis.

On the East Coast, students at Charlottetown's University of Prince Edward Island celebrated Mole Day--the unofficial holiday commemorating

Avogadro's number (6.022 x [10.sup.23])--with a 6:02 am breakfast and a celebratory ice cream cake.

This number allows scientists to calculate a different fundamental value, the Avogadro constant (or

Avogadro's number).
