There is a 1:1 equivalence of water molecules and sucrose molecules if there are a mole of each material.

Explanation:

One mole is simply a number, N_A=6.022xx10^23*mol^-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*g precisely.

"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_12H_22O_11? How many O atoms are there in each molar quantity?
