Homework Help: Chemistry 2 Ap

Posted by jecce. on Wednesday, September 10, 2008 at 12:01am.

If 10.0 g of hydrogen gar reacts with 20.0 g of oxygen gas, how much water will be made?

So far this is all i have:
(10.0g H2/1)(2molH2/2.02H2) = 9.0099 mol H2

(20.0g O2/1)(2mol O2/32g O2) = 1.25 mol O2

With the limited reactant being O2

Now what do i do?

I also have to find the yield of only 20.0g of H20 that was made.
