Question

2zn+o2=2zno

how many moles of zinc are needed to make 6 moles of zinc oxide?

Answer 1

`\boxed{\text{6 mol}}`

Step-by-step 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} * \frac{\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}.`
