# How many moles of water can be produced from 29 moles of carbon dioxide?

Start by writing down the information given to you. (29 mol CO2)

Then recall that there are 2 moles of oxygen (O) for every one mole of carbon dioxide (CO2)

From here there is 1 mole of O for every 1 mole of water.

29 mol CO2× (2 mol O)/(1 mol CO2) × (1 mol H2O)/(1 mol O) = 58 mol

why are your moles in water?? they can't swim???!!!!!!!!!!

In theory you might be able to take all the oxygen away from the CO2 and make water with it, using an excess of hydrogen, this way:

CO2 + 2 H2 → 2 H2O + C

(29 mol CO2) x (2 mol H2O / 1 mol CO2) = 58 mol H2O

(But there are all sorts of problems about this process that makes it really unlikely to happen. Besides, why would you even want to do it? There is plenty of water to be had without all this trouble.)

None, without a hydrogen source! ...and probably an energy source!

Oh well. If it's just a matter of using the CO2 as an oxygen source, then you can get 58 moles of H2O from 29 moles of CO2.

You're also going to need some source for hydrogen, otherwise you can't make any water at all. And if you are willing to add hydrogen, then why not more oxygen while you're at it?

How many moles does it take to produce a mole of water if those cute little moles could produce water?

Zero because the is no hydrogen
