#5# moles of sodium oxide

Explanation:

The reaction is:

#2Na(s)+O_2(g)->Na_2O(s)#

So, the mole ratio between sodium and sodium oxide is #2:1=2#.

Therefore, if ten moles of sodium are used, then we produce:

#10color(red)cancelcolor(black)("mol" \ Na)*(1 \ "mol" \ Na_2O)/(2color(red)cancelcolor(black)("mol" \ Na))=5 \ "mol" \ Na_2O#
