Avagadro's number is the number of objects in one mole
of that thing
- Na = 6.022*1023
A mole of hydrogen atoms contains 6.022*1023
atoms, a mole of sugar molecules contains 6.022*1023 molecules,
a mole of StarWars figures has 6.022*1023 figures. While the
latter might seem to be appoximately the number of Phantom Menace toys
sold in the first week of availability, a real mole of toys would take up
something on the order of 1% of the volume of the Earth. A mole is a very
large number. |
