Given :

2 Mg + O₂ → 2 MgO

To Find :

How many moles of magnesium oxide are formed if you burn a 2.3 mol sample of magnesium ribbon in the air.

Solution :

From given balanced chemical reaction we can see that 2 mole of Magnesium reacts with 1 mole of O₂ to produce 2 mole of MgO.

Since, there is abundance of oxygen in air.

Therefore, 2.3 moles of magnesium will produced 2.3 moles of magnesium oxide.
