# What is the purpose of the mole in chemistry?

Nov 28, 2015

You know I think the relationship between the mole and Avogadro's number, $6.022$ $\times$ ${10}^{23}$. If I have Avogadro's number ($= {N}_{A}$) of carbon atoms, then I have a mass of $12.011$ $g$ of carbon (it is not quite a whole number because there are different isotopes of carbon).
$C \left(s\right) + {O}_{2} \left(g\right) \rightarrow C {O}_{2} \left(g\right)$
