Why #4.44# #mol# precisely.

Explanation:

As for all these problems, we first need a stoichiometrically balanced equation,

#Zn(s) + 1/2O_2(g) rarr ZnO(s)#

And thus between the oxide and the starting metal, there is clearly #1:1# equivalence. So if there are 4.44 moles of zinc, clearly there are 4.44 moles of oxide. If 10 moles of zinc oxide were produced, then how moles of zinc were used?
