# How many atoms are in 1.0 mole of O_2?

This question is the same as if your were asked, $\text{how many gloves are there in 1 dozen pairs of gloves?}$
$1$ $\text{mole}$ of stuff specifies $\text{Avogadro's number, } {N}_{A} ,$ $6.022 \times {10}^{23}$ individual items of stuff.
Here I have ${N}_{A} \times {O}_{2}$ molecules. Clearly, there are $2 \times {N}_{A}$ oxygen atoms. What is the mass of this number of oxygen atoms?
