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

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

chemchemchem 
thad,
but my site says that's wrong..

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

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

chemchemchem 
Steve,
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

Annie,
yes! thank you it worked!

chemchemchem 
Annie,
