Using the equation 2H2 + O2 ==> 2H2O, determine how many grams of water is produced when 13 moles of oxygen is consumed.

13 moles Oxygen produces 13 moles of H2O.
So, how many grams is that? 
13 X 18?
234? 
looks good to me.

but my site says that's wrong..

so, what doe sit say is correct? Maybe it'll give me a clue where I messed up.

it doesn't. It just tells me to try again.

Well, if they oxygen as O2, then they'd want 13 moles of O2, that's twice as much O. So, maybe they want 468g

yes! thank you it worked!

thad do you know how to do #13?

234
