The required balanced chemical equation is 2Mg + O2----> 2MgO
Therefore from Avogadro's Law, 2 moles of Mg combine with 1 mole of Oxygen to form 2 moles of MgO.
Here, 5 moles of Oxygen take part in the reaction, which reacts with 5 X 2 = 10 moles of Magnesium.
The mass of 10 moles of Mg = Atomic Weight of Mg X 10
= 24.305 X 10 = 243.05 grams which is the required answer.
