Answer:

\boxed{\text{6 mol}}

Explanation:

(a) Balanced equation

2Zn + O₂ ⟶ 2ZnO

(b). Calculation

You want to convert moles of ZnO  to moles of Zn

The molar ratio is 2 mol Zn:2 mol ZnO

\text{Moles of Zn} =\text{6 mol ZnO} \times \dfrac{\text{2 mol Zn}}{\text{2 mol ZnO}} = \text{6 mol Zn}\\\\\text{You need }\boxed{\textbf{6 mol of Zn}}\text{ to form 6 mol of ZnO}.
