2h2 + o2 2h2o how many moles of water are produced from 13.35 mol of oxygen?

Hey there!:

Given the reaction:

2 H2 + O2  = 2 H2O

1 mol O2 2 mol H2O

13.35 mol O2 moles H2O ??

moles H2O = 13.35 * 2 / 1

moles H2O = 26.7 / 1

=> 26.7 moles of H2O

Hope That helps!

i'm assuming that the correct answer is indeed the first one/ "a"..
