I do not think you have specified the question adequately....

Explanation:

#"How many moles of water are produced when 5.00 moles of "# #"oxygen gas react?"#

And so we address the stoichiometric reaction:

#H_2(g) + 1/2O_2(g) rarr H_2O(l)#

...the which is balanced with respect to mass and charge. As indeed it must be if we purport to represent physical reality. And so we start with #160.0*g# dioxygen gas? And given the stoichiometry, we must finish with #10*mol# of water....i.e. a mass of #180*g#...and so how many grams of dihydrogen gas were involved?
