When you balance an equation, the coefficients (the numbers in front of the compounds) are Moles. You want to make sure you have an equal number on each side of the reaction.
You would multiply this number by the number of a particular ion in a molecule. So if you had 3 moles of water, that would be six moles of hydrogen ion and 3 moles of oxygen ions.

Moles is a unit of measurement in chemistry that equals 6.022x 10exp23 atoms or molecules. This is now a conversion factor since there is an equal sign!
The other relationship with moles is that one mole of a molecule will be equal to the molecule's mass in grams, which we get from the periodic table. EX: 1 mole CH4 = 16 grams CH4 (add up the 12 for Carbon and and then 4 x 1 for Hydrogen).
If you have 16 grams of CH4, then this means you have 6.022 x10exp23 molecules of CH4.
If you have a specific question, I can try to help you.

In a chemistry equation, the coefficients of reactants and products stand for mole ratios. Moles of any elements in a chemical reaction should be balanced before and after a reaction.
