The actual number chosen for the unit is arbitrary, but number of particles is still the central issue. The important thing is to have the *same* number of particles of Na and Cl. Weight only comes into it because it's totally impractical to count particles. And the particular number 6.02e23 is chosen because it happens to give a convenient relationship between number of particles and grams. If chemists had decided to use ounces instead, the number would be different. -- Greg
