Conversion factor Avogadro’s number

Table 47. Constants and Conversion Factors Avogadro s number = 6.023 X 10s per mole Electronic charge = 4.802 X 10-10 e.s.u.

Now, suppose you want to determine how many particles of sucrose are in 3.50 moles of sucrose. You know that one mole contains 6.02 X 10 representative particles. Therefore, you can write a conversion factor, Avogadro s number, that relates representative particles to moles of a substance. 

For sucrose, the representative particle is a molecule, so the number of molecules of sucrose is obtained by multiplying 3.50 moles of sucrose by the conversion factor, Avogadro s number.
