Hello,
Avogadro's number (NA), also known as a mole, is a very important number in chemistry and physics. Take an element, say copper, and look up its atomic weight. The atomic weight of copper happens to be approximately 63.55. What this means is that 63.55 grams of copper contains precisely 6.022 x 10^23 copper atoms. This means that the values of avogadro number is 6.023x10^23.
Hope this helps...
