# What is the relationship between the "mole" and "Avogadro's number"?

There is a $1 : 1$ equivalence of water molecules and sucrose molecules if there are a mole of each material.
One mole is simply a number, ${N}_{A} = 6.022 \times {10}^{23} \cdot m o {l}^{-} 1$. I could use a score or a hundred or a dozen or a Bakers' dozen. Why is the mole such an absurdly large number? It turns out that ${N}_{A}$ ""^1H atoms have a mass of $1 \cdot g$ precisely.
$\text{Avogadro's number}$ is thus the link between the micro world of atoms and the macro world of pounds, and kilos, and grams. What is the mass of 1 mole of sucrose molecules, ${C}_{12} {H}_{22} {O}_{11}$? How many $O$ atoms are there in each molar quantity?
