Malarkey. There's practically no CO2 in carbonated drinks. Sure, there's some, but you'll exhale more CO2 while you spray than you release with the spray.
For the time and effort you'd be better off with just about any other method.

LOL, Chem 101 to the rescue.
Moles are a unit of measure. It's a unit of measure like a "dozen" or a "gross". A dozen is twelve. A mole is 6.02 x 10^23. There's a lot more to it, "Avogadro's Constant" and all that, a Nobel Prize was involved, etc, etc.
Basically one mole (the name for the unit share etymology with the world "molecule") is the number of molecules necessary to create in grams the same numerical weight as the atomic weight of the molecule. So if it's pure carbon, 12 grams of carbon contains one mole of molecules since the molecular (atomic) weight of carbon is 12.
There are the same number of atoms in one mole of hydrogen as there are in one mole of gold (or anything else for that matter).
But where it gets fun is in the molecular applications. One mole of water contains the same number of molecules as one mole of glucose. But it contains a very different number of atoms.
Since water is H2O, one mole of water contains within it one mole of oxygen and two moles of hydrogen.
The mole is simply the amount of something you need to equal it's atomic weight in grams. You change the thing you're talking about, you change the gram weight but not the number of molecules/atoms involved.
Think of it this way. Say I've got a dozen whole pies. How much does that weigh? We don't know. We don't care. If I slice each of those pies into 12 pieces did I change the weight at all? Of course not. So now that I have a gross (a dozen dozen, or 144) slices I haven't broken the laws of physics. I've just changed what I'm counting.
