2 moles of ZnO are produced if 1 mole of Zn and 2 moles of
is required.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 ×
of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Balanced equation:
→ 
For 2 moles of Zinc, we need 1 mol of Oxygen to produce 2 moles of Zinc oxide
For 1 mole Zn, we need 2 mol
to produce 2 moles ZnO only.
Hence, 2 moles ZnO is produced.
