So I'm trying to figure out the amount of sodium bicarbonate and acetic acid to use to move a balloon over 2 cm

I didn't pay attention in stoichiometry unit, so I'm no help.

We're using a water bottle that is 16.9 Fl oz/500ml

Take 3 grams of potassium chloride, put it in the bottle, and then shut up
United as One, Divided by Zero
That sounds like Physics moreso than Chemistry.

And we need a mass for the balloon.
"Virtually no one who is taught Relativity continues to read the Bible."

We'll need the concentration of both, and that's a very vague result your looking for, it'll need a lot of trial and error
oh, like the grams and stuff??

whats the equation I use to find it myself?

I'll find the mass for the balloon- 3.04 g

You'll need more than just chemistry I think. I say go trial and error, keep track of your results and see if you can figure what affects it most. Unless you make it in one of the trials, then just use that.
what do you mean by move a balloon... be more specific

We have to fill a bottle with baking soda and vinegar to fill the balloon up with the reactant- Co2

ok so im assuming you dont have to calculate the added pressure from the resistance of the balloon.. what you need is to figure out the volume of the balloon when it has a 2cm radius, add that to the volume of the bottle... and then figure out how many moles of CO2 occupy that volume at room temperature and then figure out how many moles of each reactant is required

my previous post was assuming there was no air in the bottle... seeing as there is air in the bottle you only need to use the volume of the balloon

How do I figure out the mols of Co2 that would occupy that space??

I failed stochiometery
