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?
