Answer 2

A mole is a number of something just like a dozen. A mole is just a lot more of that something.

Answer 3

.0069 moles*(6.022x10^23 atoms/1 mol) = 4.16x10^21 atoms

Answer 4

http://en.wikipedia.org/wiki/Avogadro_constant

The Avogadro number is the number of atoms/molecules in 1 mol of a substance. You have 0.0069 mol so...? :)

Answer 5

\[1\ mol = 6.022 \times 10^{23} \ objects\]
In this case, the "objects" are your atoms. So now you can set up a conversion equation:
\[(0.0069\ mol)(\frac{6.022\times10^{23}\ atoms}{1\ mol})=4.2\times10^{21}\ atoms\]
Multiplying by that conversion factor is equivalent to multiplying by one, but it changes the unites of the expression!
